The flexible erase architecture of the AT26DF321, with its erase granularity as small as 4-Kbytes, makes it ideal for data storage as well, eliminating the need for additional data storage EEPROM devices.The physical sectoring and the erase block sizes of the AT26DF321 have been opti-mized to meet the needs of today's code and data storage applications. By optimizing the size of the physical sectors and erase blocks, the memory space can be used much more efficiently. Because certain code modules and data storage segments must reside by themselves in their own protected sectors, the wasted and unused memory space that occurs with large sectored and large block erase Flash memory devices can be greatly reduced. This increased memory space efficiency allows addi-tional code routines and data storage segments to be added while still maintaining thesame overall device density.23633C–DFLASH–08/06AT26DF321 [Preliminary]The AT26DF321 also offers a sophisticated method for protecting individual sectors against erroneous or malicious program and erase operations. By providing the ability to individually pro-tect and unprotect sectors, a system can unprotect a specific sector to modify its contents while keeping the remaining sectors of the memory array securely protected. This is useful in applica-tions where program code is patched or updated on a subroutine or module basis, or in applications where data storage segments need to be modified without running the risk of errant modifications to the program code segments. In addition to individual sector protection capabili-ties, the AT26DF321 incorporates Global Protect and Global Unprotect features that allow the entire memory array to be either protected or unprotected all at once. This reduces overhead during the manufacturing process since sectors do not have to be unprotected one-by-one prior to initial programming.Specifically designed for use in 3-volt systems, the AT26DF321 supports read, program, and erase operations with a supply voltage range of 2.7V to 3.6V. No separate voltage is required for programming and erasing.2.Pin Descriptions and PinoutsTable 2-1.Pin DescriptionsSymbolName and FunctionAsserted StateTypeCS CHIP SELECT : Asserting the CS pin selects the device. When the CS pin is deasserted, thedevice will be deselected and normally be placed in standby mode (not Deep Power-Down mode), and the SO pin will be in a high-impedance state. When the device is deselected, data will not be accepted on the SI pin.A high-to-low transition on the CS pin is required to start an operation, and a low-to-high transition is required to end an operation. When ending an internally self-timed operation such as a program or erase cycle, the device will not enter the standby mode until the completion of the operation.Low InputSCK SERIAL CLOCK : This pin is used to provide a clock to the device and is used to control the flow of data to and from the device. Command, address, and input data present on the SI pin is always latched on the rising edge of SCK, while output data on the SO pin is always clocked out on the falling edge of SCK.InputSI SERIAL INPUT : The SI pin is used to shift data into the device. The SI pin is used for all data input including command and address sequences. Data on the SI pin is always latched on the rising edge of SCK.InputSO SERIAL OUTPUT : The SO pin is used to shift data out from the device. Data on the SO pin is always clocked out on the falling edge of SCK.OutputWP WRITE PROTECT : The WP pin controls the hardware locking feature of the device. Please refer to “Protection Commands and Features” on page 11 for more details on protection features and the WP pin.The WP pin is internally pulled-high and may be left floating if hardware controlled protection will not be used. However, it is recommended that the WP pin also be externally connected to V CC whenever possible.Low InputV CC DEVICE POWER SUPPLY : The V CC pin is used to supply the source voltage to the device.Operations at invalid V CC voltages may produce spurious results and should not be attempted.Power GNDGROUND : The ground reference for the power supply. GND should be connected to the system ground.Power33633C–DFLASH–08/06AT26DF321 [Preliminary]3.Block Diagram4.Memory ArrayTo provide the greatest flexibility, the memory array of the AT26DF321 can be erased in four lev-els of granularity including a full chip erase. In addition, the array has been divided into physical sectors of uniform size, of which each sector can be individually protected from program and erase operations. The size of the physical sectors is optimized for both code and data storage applications, allowing both code and data segments to reside in their own isolated regions.Figure 4-1 on page 4 illustrates the breakdown of each erase level as well as the break-down of each physical sector.Figure 2-1.8-SOIC Top ViewFigure 2-2.16-SOIC Top View43633C–DFLASH–08/06AT26DF321 [Preliminary]Figure 4-1.Memory Architecture Diagram53633C–DFLASH–08/06AT26DF321 [Preliminary]5.Device OperationThe AT26DF321 is controlled by a set of instructions that are sent from a host controller, com-monly referred to as the SPI Master. The SPI Master communicates with the AT26DF321 via the SPI bus which is comprised of four signal lines: Chip Select (CS), Serial Clock (SCK), Serial Input (SI), and Serial Output (SO).The SPI protocol defines a total of four modes of operation (mode 0, 1, 2, or 3) with each mode differing in respect to the SCK polarity and phase and how the polarity and phase control the flow of data on the SPI bus. The AT26DF321 supports the two most common modes, SPI Modes 0 and 3. The only difference between SPI Modes 0 and 3 is the polarity of the SCK signal when in the inactive state (when the SPI Master is in standby mode and not transferring any data). With SPI Modes 0 and 3, data is always latched in on the rising edge of SCK and always output on the falling edge of SCK.Figure 5-1.SPI Mode 0 and 3mands and Addressingpin has been asserted, the SPI Master must then clock out a valid 8-bit opcode on the SPI bus.Following the opcode, instruction dependent information such as address and data bytes would then be clocked out by the SPI Master. All opcode, address, and data bytes are transferred with Opcodes not supported by the AT26DF321 will be ignored by the device and no operation will be started. The device will continue to ignore any data presented on the SI pin until the start of the next operation (CS pin being deasserted and then reasserted). In addition, if the CS pin is deas-serted before complete opcode and address information is sent to the device, then no operation will be performed and the device will simply return to the idle state and wait for the next operation.Addressing of the device requires a total of three bytes of information to be sent, representing address bits A23-A0.

The device incorporates an internal address counter that automatically increments on every clock cycle.Two opcodes, 0Bh and 03h, can be used for the Read Array command. The use of each opcode depends on the maximum SCK frequency that will be used to read data from the device. The 0Bh opcode can be used at any SCK frequency up to the maximum specified by f SCK . The 03h opcode can be used for lower frequency read operations up to the maximum specified by f RDLF .To perform the Read Array operation, the CS pin must first be asserted and the appropriate opcode (0Bh or 03h) must be clocked into the device. After the opcode has been clocked in, the three address bytes must be clocked in to specify the starting address location of the first byte to read within the memory array. If the 0Bh opcode is used, then one don’t care byte must also be clocked in after the three address bytes.After the three address bytes (and the one don’t care byte if using opcode 0Bh) have been clocked in, additional clock cycles will result in serial data being output on the SO pin. The data is always output with the MSB of a byte first. When the last byte (3FFFFFh) of the memory array has been read, the device will continue reading back at the beginning of the array (000000h). No delays will be incurred when wrapping around from the end of the array to the beginning of the array.ance state. The CS pin can be deasserted at any time and does not require that a full byte of data be read.Figure 7-1.Read Array – 0Bh OpcodeFigure 7-2.Read Array – 03h Opcode83633C–DFLASH–08/06AT26DF321 [Preliminary]8.Program and Erase Commands8.1Byte/Page ProgramThe Byte/Page Program command allows anywhere from a single byte of data to 256 bytes of data to be programmed into previously erased memory locations. An erased memory location is one that has all eight bits set to the logical “1” state (a byte value of FFh). Before a Byte/Page Program command can be started, the Write Enable command must have been previously issued to the device (see Write Enable command description) to set the Write Enable Latch (WEL) bit of the Status Register to a logical “1” state.To perform a Byte/Page Program command, an opcode of 02h must be clocked into the device followed by the three address bytes denoting the first byte location of the memory array to begin programming at. After the address bytes have been clocked in, data can then be clocked into the device and will be stored in an internal buffer.If the starting memory address denoted by A23-A0 does not fall on an even 256-byte page boundary (A7-A0 are not all 0), then special circumstances regarding which memory locations will be programmed will apply. In this situation, any data that is sent to the device that goes beyond the end of the page will wrap around back to the beginning of the same page. For exam-ple, if the starting address denoted by A23-A0 is 0000FEh, and three bytes of data are sent to the device, then the first two bytes of data will be programmed at addresses 0000FEh and 0000FFh while the last byte of data will be programmed at address 000000h. The remaining bytes in the page (addresses 000001h through 0000FDh) will be unaffected and will not change.In addition, if more than 256 bytes of data are sent to the device, then only the last 256 bytes sent will be latched into the internal buffer.When the CS pin is deasserted, the device will take the data stored in the internal buffer and pro-gram it into the appropriate memory array locations based on the starting address specified by A23-A0 and the number of complete data bytes sent to the device. If less than 256 bytes of data were sent to the device, then the remaining bytes within the page will not be altered. The pro-gramming of the data bytes is internally self-timed and should take place in a time of t PP .The three address bytes and at least one complete byte of data must be clocked into the device before the CS pin is deasserted; otherwise, the device will abort the operation and no data will be programmed into the memory array. In addition, if the address specified by A23-A0 points to a memory location within a sector that is in the protected state (see “Protect Sector” on page 12), then the Byte/Page Program command will not be executed, and the device will return to the idle state once the CS pin has been deasserted. The WEL bit in the Status Register will be reset back to the logical “0” state if the program cycle aborts due to an incomplete address being sent,an incomplete byte of data being sent, or because the memory location to be programmed is protected.While the device is programming, the Status Register can be read and will indicate that the device is busy. For faster throughput, it is recommended that the Status Register be polled rather than waiting the t PP time to determine if the data bytes have finished programming. At some point before the program cycle completes, the WEL bit in the Status Register will be reset back to the logical “0” state.93633C–DFLASH–08/06AT26DF321 [Preliminary]Figure 8-1.Byte ProgramFigure 8-2.Page Program8.2Block EraseA block of 4K-, 32K-, or 64K-bytes can be erased (all bits set to the logical “1” state) in a single operation by using one of three different opcodes for the Block Erase command. An opcode of 20h is used for a 4K-byte erase, an opcode of 52h is used for a 32K-byte erase, and an opcode of D8h is used for a 64K-byte erase. Before a Block Erase command can be started, the Write Enable command must have been previously issued to the device to set the WEL bit of the Sta-tus Register to a logical “1” state.52h, or D8h) must be clocked into the device. After the opcode has been clocked in, the three address bytes specifying an address within the 4K-, 32K-, or 64K-byte block to be erased must be clocked in. Any additional data clocked into the device will be ignored. When the CS pin is deasserted, the device will erase the appropriate block. The erasing of the block is internally self-timed and should take place in a time of t BLKE .Since the Block Erase command erases a region of bytes, the lower order address bits do not need to be decoded by the device. Therefore, for a 4K-byte erase, address bits A11-A0 will be ignored by the device and their values can be either a logical “1” or “0”. For a 32K-byte erase,address bits A14-A0 will be ignored, and for a 64K-byte erase, address bits A15-A0 will be ignored by the device. Despite the lower order address bits not being decoded by the device, the complete three address bytes must still be clocked into the device before the CS pin is deas-serted; otherwise, the device will abort the operation and no erase operation will be performed.103633C–DFLASH–08/06AT26DF321 [Preliminary]If the address specified by A23-A0 points to a memory location within a sector that is in the pro-tected state, then the Block Erase command will not be executed, and the device will return to The WEL bit in the Status Register will be reset back to the logical “0” state if the erase cycle aborts due to an incomplete address being sent or because a memory location within the region to be erased is protected.While the device is executing a successful erase cycle, the Status Register can be read and will indicate that the device is busy. For faster throughput, it is recommended that the Status Regis-ter be polled rather than waiting the t BLKE time to determine if the device has finished erasing. At some point before the erase cycle completes, the WEL bit in the Status Register will be reset back to the logical “0” state.Figure 8-3.Block Erase8.3Chip EraseThe entire memory array can be erased in a single operation by using the Chip Erase command.Before a Chip Erase command can be started, the Write Enable command must have been pre-viously issued to the device to set the WEL bit of the Status Register to a logical “1” state.Two opcodes, 60h and C7h, can be used for the Chip Erase command. There is no difference in device functionality when utilizing the two opcodes, so they can be used interchangeably. To perform a Chip Erase, one of the two opcodes (60h or C7h) must be clocked into the device.Since the entire memory array is to be erased, no address bytes need to be clocked into the device, and any data clocked in after the opcode will be ignored. When the CS pin is deasserted,the device will erase the entire memory array. The erasing of the device is internally self-timed and should take place in a time of t CHPE .wise, no erase will be performed. In addition, if any sector of the memory array is in the protected state, then the Chip Erase command will not be executed, and the device will return to the idle state once the CS pin has been deasserted. The WEL bit in the Status Register will be reset back to the logical “0” state if a sector is in the protected state.While the device is executing a successful erase cycle, the Status Register can be read and will indicate that the device is busy. For faster throughput, it is recommended that the Status Regis-ter be polled rather than waiting the t CHPE time to determine if the device has finished erasing. At some point before the erase cycle completes, the WEL bit in the Status Register will be reset back to the logical “0” state.AT26DF321 [Preliminary] Figure 8-4.Chip Erase9.Protection Commands and Features9.1Write EnableThe Write Enable command is used to set the Write Enable Latch (WEL) bit in the Status Regis-ter to a logical “1” state. The WEL bit must be set before a program, erase, Protect Sector,Unprotect Sector, or Write Status Register command can be executed. This makes the issuanceof these commands a two step process, thereby reducing the chances of a command beingaccidentally or erroneously executed. If the WEL bit in the Status Register is not set prior to theissuance of one of these commands, then the command will not be executed.must be clocked into the device. No address bytes need to be clocked into the device, and anythe Status Register will be set to a logical “1”. The complete opcode must be clocked into thestate of the WEL bit will not change.Figure 9-1.Write Enable9.2Write DisableThe Write Disable command is used to reset the Write Enable Latch (WEL) bit in the Status Reg-ister to the logical “0” state. With the WEL bit reset, all program, erase, Protect Sector, UnprotectSector, and Write Status Register commands will not be executed. The Write Disable commandis also used to exit the Sequential Program Mode. Other conditions can also cause the WEL bitto be reset; for more details, refer to the WEL bit section of the Status Register description onpage 20.must be clocked into the device. No address bytes need to be clocked into the device, and anythe Status Register will be reset to a logical “0”. The complete opcode must be clocked into thestate of the WEL bit will not change.Figure 9-2.Write Disable9.3Protect SectorEvery physical sector of the device has a corresponding single-bit Sector Protection Registerthat is used to control the software protection of a sector. Upon device power-up or after adevice reset, each Sector Protection Register will default to the logical “1” state indicating that allsectors are protected and cannot be programmed or erased.Issuing the Protect Sector command to a particular sector address will set the correspondingSector Protection Register to the logical “1” state. The following table outlines the two states ofthe Sector Protection Registers.Table 9-1.Sector Protection Register ValuesValue Sector Protection Status0Sector is unprotected and can be programmed and erased.1Sector is protected and cannot be programmed or erased. This is the default state.Before the Protect Sector command can be issued, the Write Enable command must have beenpreviously issued to set the WEL bit in the Status Register to a logical “1”. To issue the ProtectSector command, the CS pin must first be asserted and the opcode of 36h must be clocked intothe device followed by three address bytes designating any address within the sector to belocked. Any additional data clocked into the device will be ignored. When the CS pin is deas-serted, the Sector Protection Register corresponding to the physical sector addressed by A23-A0 will be set to the logical “1” state, and the sector itself will then be protected from programAT26DF321 [Preliminary] and erase operations. In addition, the WEL bit in the Status Register will be reset back to the log-ical “0” state.serted; otherwise, the device will abort the operation, the state of the Sector Protection Registerwill be unchanged, and the WEL bit in the Status Register will be reset to a logical “0”.As a safeguard against accidental or erroneous protecting or unprotecting of sectors, the SectorProtection Registers can themselves be locked from updates by using the SPRL (Sector Protec-tion Registers Locked) bit of the Status Register (please refer to “Status Register Commands”on page 19 for more details). If the Sector Protection Registers are locked, then any attempts toissue the Protect Sector command will be ignored, and the device will reset the WEL bit in thedeasserted.Figure 9-3.Protect Sector9.4Unprotect SectorIssuing the Unprotect Sector command to a particular sector address will reset the correspond-ing Sector Protection Register to the logical “0” state (see Table 9-1 on page 12 for SectorProtection Register values). Every physical sector of the device has a corresponding single-bitSector Protection Register that is used to control the software protection of a sector.Before the Unprotect Sector command can be issued, the Write Enable command must havebeen previously issued to set the WEL bit in the Status Register to a logical “1”. To issue theUnprotect Sector command, the CS pin must first be asserted and the opcode of 39h must beclocked into the device. After the opcode has been clocked in, the three address bytes designat-ing any address within the sector to be unlocked must be clocked in. Any additional data clockedtor Protection Register corresponding to the sector addressed by A23-A0 will be reset to thelogical “0” state, and the sector itself will be unprotected. In addition, the WEL bit in the StatusRegister will be reset back to the logical “0” state.serted; otherwise, the device will abort the operation, the state of the Sector Protection Registerwill be unchanged, and the WEL bit in the Status Register will be reset to a logical “0”.As a safeguard against accidental or erroneous locking or unlocking of sectors, the Sector Pro-tection Registers can themselves be locked from updates by using the SPRL (Sector ProtectionRegisters Locked) bit of the Status Register (please refer to “Status Register Commands” onpage 19 for more details). If the Sector Protection Registers are locked, then any attempts toissue the Unprotect Sector command will be ignored, and the device will reset the WEL bit in theStatus Register back to a logical “0” and return to the idle state once the CS pin has beendeasserted.Figure 9-4.Unprotect Sector9.5Global Protect/UnprotectThe Global Protect and Global Unprotect features can work in conjunction with the Protect Sec-tor and Unprotect Sector functions. For example, a system can globally protect the entirememory array and then use the Unprotect Sector command to individually unprotect certain sec-tors and individually reprotect them later by using the Protect Sector command. Likewise, asystem can globally unprotect the entire memory array and then individually protect certain sec-tors as needed.Performing a Global Protect or Global Unprotect is accomplished by writing a certain combina-tion of data to the Status Register using the Write Status Register command (see “Write StatusRegister” section on page 21 for command execution details). The Write Status Register com-mand is also used to modify the SPRL (Sector Protection Registers Locked) bit to controlhardware and software locking.To perform a Global Protect, the appropriate WP pin and SPRL conditions must be met and thesystem must write a logical “1” to bits 5, 4, 3, and 2 of the Status Register. Conversely, to per-form a Global Unprotect, the same WP and SPRL conditions must be met but the system mustwrite a logical “0” to bits 5, 4, 3, and 2 of the Status Register. Table 9-2 details the conditionsnecessary for a Global Protect or Global Unprotect to be performed.AT26DF321 [Preliminary]Essentially, if the SPRL bit of the Status Register is in the logical “0” state (Sector Protection Registers are not locked), then writing a 00h to the Status Register will perform a Global Unpro-tect without changing the state of the SPRL bit. Similarly, writing a 7Fh to the Status Register will perform a Global Protect and keep the SPRL bit in the logical “0” state. The SPRL bit can, of course, be changed to a logical “1” by writing an FFh if software-locking or hardware-locking is desired along with the Global Protect.Table 9-2.Valid SPRL and Global Protect/Unprotect ConditionsWP StateCurrent SPRL Value New Write Status Register Data Protection OperationNew SPRL Value Bit7 6 5 4 3 2 1 000 x 0 0 0 0 x x 0 x 0 0 0 1 x x↕0 x 1 1 1 0 x x 0 x 1 1 1 1 x x1 x 0 0 0 0 x x 1 x 0 0 0 1 x x↕1 x 1 1 1 0 x x 1 x 1 1 1 1 x xGlobal Unprotect – all Sector Protection Registers reset to 0No change to current protection.No change to current protection.No change to current protection.Global Protect – all Sector Protection Registers set to 1Global Unprotect – all Sector Protection Registers reset to 0No change to current protection.No change to current protection.No change to current protection.Global Protect – all Sector Protection Registers set to 100000111111x x x x x x x xNo change to the current protection level.

The CPU contains 13 registers. R0, R1, R2, R3, A0, A1, and FB configure a register bank. There are two sets of register bank.2.1Data Registers (R0, R1, R2, and R3)R0 is a 16-bit register for transfer, arithmetic, and logic operations. The same applies to R1 to R3. R0 can be split into high-order bits (R0H) and low-order bits (R0L) to be used separately as 8-bit data registers. R1H and R1L are analogous to R0H and R0L. R2 can be combined with R0 and used as a 32-bit data register (R2R0). R3R1 is analogous to R2R0.2.2Address Registers (A0 and A1)A0 is a 16-bit register for address register indirect addressing and address register relative addressing. It is also used for transfer, arithmetic, and logic operations. A1 is analogous to A0. A1 can be combined with A0 and as a 32-bit address register (A1A0).2.3Frame Base Register (FB)FB is a 16-bit register for FB relative addressing.2.4Interrupt Table Register (INTB)INTB is a 20-bit register that indicates the start address of an interrupt vector table.2.5Program Counter (PC)PC is 20 bits wide and indicates the address of the next instruction to be executed.2.6User Stack Pointer (USP) and Interrupt Stack Pointer (ISP)The stack pointers (SP), USP, and ISP, are each 16 bits wide. The U flag of FLG is used to switch betweenUSP and ISP.2.7Static Base Register (SB)SB is a 16-bit register for SB relative addressing.2.8Flag Register (FLG)FLG is an 11-bit register indicating the CPU state.2.8.1Carry Flag (C)The C flag retains carry, borrow, or shift-out bits that have been generated by the arithmetic and logic unit.2.8.2Debug Flag (D)The D flag is for debugging only. Set it to 0.2.8.3Zero Flag (Z)The Z flag is set to 1 when an arithmetic operation results in 0; otherwise to 0.2.8.4Sign Flag (S)The S flag is set to 1 when an arithmetic operation results in a negative value; otherwise to 0.2.8.5Register Bank Select Flag (B)Register bank 0 is selected when the B flag is 0. Register bank 1 is selected when this flag is set to 1.2.8.6Overflow Flag (O)The O flag is set to 1 when an operation results in an overflow; otherwise to 0.2.8.7Interrupt Enable Flag (I)The I flag enables maskable interrupts.Interrupt are disabled when the I flag is set to 0, and are enabled when the I flag is set to 1. The I flag is set to 0 when an interrupt request is acknowledged.2.8.8Stack Pointer Select Flag (U)ISP is selected when the U flag is set to 0; USP is selected when the U flag is set to 1.The U flag is set to 0 when a hardware interrupt request is acknowledged or the INT instruction of software interrupt numbers 0 to 31 is executed.2.8.9Processor Interrupt Priority Level (IPL)IPL is 3 bits wide and assigns processor interrupt priority levels from level 0 to level 7.If a requested interrupt has higher priority than IPL, the interrupt is enabled.2.8.10Reserved BitIf necessary, set to 0. When read, the content is undefined.3.Memory3.1R8C/2A GroupFigure 3.1 is a Memory Map of R8C/2A Group. The R8C/2A group has 1 Mbyte of address space from addresses 00000h to FFFFFh.The internal ROM is allocated lower addresses, beginning with address 0FFFFh. For example, a 48-Kbyte internal ROM area is allocated addresses 04000h to 0FFFFh.The fixed interrupt vector table is allocated addresses 0FFDCh to 0FFFFh. They store the starting address of each interrupt routine.The internal RAM is allocated higher addresses, beginning with address 00400h. For example, a 2.5-Kbyte internal RAM area is allocated addresses 00400h to 00DFFh. The internal RAM is used not only for storing data but also for calling subroutines and as stacks when interrupt requests are acknowledged.Special function registers (SFRs) are allocated addresses 00000h to 002FFh. The peripheral function control registers are allocated here. All addresses within the SFR, which have nothing allocated are reserved for future use and cannot be accessed by users.3.2R8C/2B GroupFigure 3.2 is a Memory Map of R8C/2B Group. The R8C/2B group has 1 Mbyte of address space from addresses 00000h to FFFFFh.The internal ROM (program ROM) is allocated lower addresses, beginning with address 0FFFFh. For example, a 48-Kbyte internal ROM area is allocated addresses 04000h to 0FFFFh.The fixed interrupt vector table is allocated addresses 0FFDCh to 0FFFFh. They store the starting address of each interrupt routine.The internal ROM (data flash) is allocated addresses 02400h to 02BFFh.The internal RAM area is allocated higher addresses, beginning with address 00400h. For example, a 2.5-Kbyte internal RAM is allocated addresses 00400h to 00DFFh. The internal RAM is used not only for storing data but also for calling subroutines and as stacks when interrupt requests are acknowledged.Special function registers (SFRs) are allocated addresses 00000h to 002FFh. The peripheral function control registers are allocated here.

Central Processing Unit (CPU)2.Central Processing Unit (CPU)Figure 2.1 shows the CPU Registers. The CPU contains 13 registers. Of these, R0, R1, R2, R3, A0, A1, and FB comprise a register bank. Two sets of register banks are provided.2.1Data Registers (R0, R1, R2 and R3)R0 is a 16-bit register for transfer, arithmetic, and logic operations. The same applies to R1 to R3.R0 can be split into high-order bit (R0H) and low-order bit (R0L) to be used separately as 8-bit data registers. The same applies to R1H and R1L as R0H and R0L. R2 can be combined with R0 to be used as a 32-bit data register (R2R0). The same applies R3R1 as R2R0.2.2Address Registers (A0 and A1)A0 is a 16-bit register for address register indirect addressing and address register relative addressing. They also are used for transfer, arithmetic and logic operations. The same applies to A1 as A0.A1 can be combined with A0 to be used a 32-bit address register (A1A0).2.3Frame Base Register (FB)FB is a 16-bit register for FB relative addressing.2.4Interrupt Table Register (INTB)INTB, a 20-bit register, indicates the start address of an interrupt vector table.2.5Program Counter (PC)PC, 20 bits wide, indicates the address of an instruction to be executed.2.6User Stack Pointer (USP) and Interrupt Stack Pointer (ISP)The stack pointer (SP), USP and ISP, are 16 bits wide each.The U flag of FLG is used to switch between USP and ISP.2.7Static Base Register (SB)SB is a 16-bit register for SB relative addressing.2.8Flag Register (FLG)FLG is a 11-bit register indicating the CPU status.2.8.1Carry Flag (C)The C flag retains a carry, borrow, or shift-out bit that has occurred in the arithmetic and logic unit.2.8.2Debug Flag (D)The D flag is for debug only. Set to 0.2.8.3Zero Flag (Z)The Z flag is set to 1 when an arithmetic operation resulted in 0; otherwise, 0.2.8.4Sign Flag (S)The S flag is set to 1 when an arithmetic operation resulted in a negative value; otherwise, 0.2.8.5Register Bank Select Flag (B)The register bank 0 is selected when the B flag is 0. The register bank 1 is selected when this flag is set to 1.2.8.6Overflow Flag (O)The O flag is set to 1 when the operation resulted in an overflow; otherwise, 0.2.8.7Interrupt Enable Flag (I)The I flag enables a maskable interrupt.An interrupt is disabled when the I flag is set to 0, and are enabled when the I flag is set to 1. The I flag is set to0 when an interrupt request is acknowledged.2.8.8Stack Pointer Select Flag (U)ISP is selected when the U flag is set to 0; USP is selected when the U flag is set to 1.The U flag is set to 0 when a hardware interrupt request is acknowledged or the INT instruction of software interrupt numbers. 0 to 31 is executed.2.8.9Processor Interrupt Priority Level (IPL)IPL, 3 bits wide, assigns processor interrupt priority levels from level 0 to level 7.If a requested interrupt has greater priority than IPL, the interrupt is enabled.2.8.10Reserved BitIf necessary, set to 0. When read, the content is undefined.3.Memory3.1R8C/22 GroupFigure 3.1 shows a Memory Map of R8C/22 Group. The R8C/22 Group has 1 Mbyte of address space from address 00000h to FFFFFh.The internal ROM is allocated lower addresses, beginning with address 0FFFFh. For example, a 48-Kbyte internal ROM is allocated addresses 04000h to 0FFFFh.The fixed interrupt vector table is allocated addresses 0FFDCh to 0FFFFh. They store the starting address of each interrupt routine.The internal RAM is allocated higher addresses, beginning with address 00400h. For example, a 2.5 Kbyte internal RAM is allocated addresses 00400h to 00DFFh. The internal RAM is used not only for storing data but also for calling subroutines and as stacks when interrupt requests are acknowledged.Special function registers (SFR) are allocated addresses 00000h to 002FFh and 01300h to 0147Fh (SFR area for CAN). The peripheral function control registers are allocated here. All addresses within the SFR, which have nothing allocated are reserved for future user and cannot be accessed by users.3.2R8C/23 GroupFigure 3.2 shows a Memory Map of R8C/23 Group. The R8C/23 Group has 1 Mbyte of address space from address 00000h to FFFFFh.The internal ROM (program ROM) is allocated lower addresses, beginning with address 0FFFFh. For example, a 48-Kbyte internal ROM is allocated addresses 04000h to 0FFFFh.The fixed interrupt vector table is allocated addresses 0FFDCh to 0FFFFh. They store the starting address of each interrupt routine.The internal ROM (data flash) is allocated addresses 02400h to 02BFFh.The internal RAM is allocated higher addresses, beginning with address 00400h. For example, a 2.5-Kbyte internal RAM is allocated addresses 00400h to 00DFFh. The internal RAM is used not only for storing data but also for calling subroutines and as stacks when interrupt requests are acknowledged.Special function registers (SFR) are allocated addresses 00000h to 002FFh and 01300h to 0147Fh (SFR area for CAN).

Central Processing Unit (CPU)2.Central Processing Unit (CPU)Figure 2.1 shows the CPU Registers. The CPU contains 13 registers. Of these, R0, R1, R2, R3, A0, A1, and FB comprise a register bank. Two sets of register banks are provided.2.1Data Registers (R0, R1, R2 and R3)R0 is a 16-bit register for transfer, arithmetic, and logic operations. The same applies to R1 to R3.R0 can be split into high-order bit (R0H) and low-order bit (R0L) to be used separately as 8-bit data registers. The same applies to R1H and R1L as R0H and R0L. R2 can be combined with R0 to be used as a 32-bit data register (R2R0). The same applies R3R1 as R2R0.2.2Address Registers (A0 and A1)A0 is a 16-bit register for address register indirect addressing and address register relative addressing. They also are used for transfer, arithmetic and logic operations. The same applies to A1 as A0.A1 can be combined with A0 to be used a 32-bit address register (A1A0).2.3Frame Base Register (FB)FB is a 16-bit register for FB relative addressing.2.4Interrupt Table Register (INTB)INTB, a 20-bit register, indicates the start address of an interrupt vector table.2.5Program Counter (PC)PC, 20 bits wide, indicates the address of an instruction to be executed.2.6User Stack Pointer (USP) and Interrupt Stack Pointer (ISP)The stack pointer (SP), USP and ISP, are 16 bits wide each.The U flag of FLG is used to switch between USP and ISP.2.7Static Base Register (SB)SB is a 16-bit register for SB relative addressing.2.8Flag Register (FLG)FLG is a 11-bit register indicating the CPU status.2.8.1Carry Flag (C)The C flag retains a carry, borrow, or shift-out bit that has occurred in the arithmetic and logic unit.2.8.2Debug Flag (D)The D flag is for debug only. Set to 0.2.8.3Zero Flag (Z)The Z flag is set to 1 when an arithmetic operation resulted in 0; otherwise, 0.2.8.4Sign Flag (S)The S flag is set to 1 when an arithmetic operation resulted in a negative value; otherwise, 0.2.8.5Register Bank Select Flag (B)The register bank 0 is selected when the B flag is 0. The register bank 1 is selected when this flag is set to 1.2.8.6Overflow Flag (O)The O flag is set to 1 when the operation resulted in an overflow; otherwise, 0.2.8.7Interrupt Enable Flag (I)The I flag enables a maskable interrupt.An interrupt is disabled when the I flag is set to 0, and are enabled when the I flag is set to 1. The I flag is set to0 when an interrupt request is acknowledged.2.8.8Stack Pointer Select Flag (U)ISP is selected when the U flag is set to 0; USP is selected when the U flag is set to 1.The U flag is set to 0 when a hardware interrupt request is acknowledged or the INT instruction of software interrupt numbers. 0 to 31 is executed.2.8.9Processor Interrupt Priority Level (IPL)IPL, 3 bits wide, assigns processor interrupt priority levels from level 0 to level 7.If a requested interrupt has greater priority than IPL, the interrupt is enabled.2.8.10Reserved BitIf necessary, set to 0. When read, the content is undefined.3.Memory3.1R8C/22 GroupFigure 3.1 shows a Memory Map of R8C/22 Group. The R8C/22 Group has 1 Mbyte of address space from address 00000h to FFFFFh.The internal ROM is allocated lower addresses, beginning with address 0FFFFh. For example, a 48-Kbyte internal ROM is allocated addresses 04000h to 0FFFFh.The fixed interrupt vector table is allocated addresses 0FFDCh to 0FFFFh. They store the starting address of each interrupt routine.The internal RAM is allocated higher addresses, beginning with address 00400h. For example, a 2.5 Kbyte internal RAM is allocated addresses 00400h to 00DFFh. The internal RAM is used not only for storing data but also for calling subroutines and as stacks when interrupt requests are acknowledged.Special function registers (SFR) are allocated addresses 00000h to 002FFh and 01300h to 0147Fh (SFR area for CAN). The peripheral function control registers are allocated here. All addresses within the SFR, which have nothing allocated are reserved for future user and cannot be accessed by users.3.2R8C/23 GroupFigure 3.2 shows a Memory Map of R8C/23 Group. The R8C/23 Group has 1 Mbyte of address space from address 00000h to FFFFFh.The internal ROM (program ROM) is allocated lower addresses, beginning with address 0FFFFh. For example, a 48-Kbyte internal ROM is allocated addresses 04000h to 0FFFFh.The fixed interrupt vector table is allocated addresses 0FFDCh to 0FFFFh. They store the starting address of each interrupt routine.The internal ROM (data flash) is allocated addresses 02400h to 02BFFh.The internal RAM is allocated higher addresses, beginning with address 00400h. For example, a 2.5-Kbyte internal RAM is allocated addresses 00400h to 00DFFh. The internal RAM is used not only for storing data but also for calling subroutines and as stacks when interrupt requests are acknowledged.Special function registers (SFR) are allocated addresses 00000h to 002FFh and 01300h to 0147Fh (SFR area for CAN). The peripheral function control registers are allocated them. All addresses within the SFR, which have nothing allocated are reserved for future use and cannot be accessed by users.4.Special Function Registers (SFRs)An SFR (special function register) is a control register for a peripheral function.Table 4.1 to Table 4.13 list the SFR Information.Table 4.1SFR Information (1)(1)Address Register Symbol After reset 0000h0001h0002h0003h0004h Processor Mode Register 0PM000h0005h Processor Mode Register 1PM100h0006h System Clock Control Register 0CM001101000b0007h System Clock Control Register 1CM100100000b 0008h0009h000Ah Protect Register PRCR00h000Bh000Ch Oscillation Stop Detection Register OCD00000100b 000Dh Watchdog Timer Reset Register WDTR XXh000Eh Watchdog Timer Start Register WDTS XXh000Fh Watchdog Timer Control Register WDC00X11111b0010h Address Match Interrupt Register 0RMAD000h0011h00h0012h00h0013h Address Match Interrupt Enable Register AIER00h0014h Address Match Interrupt Register 1RMAD100h0015h00h0016h00h0017h0018h0019h001Ah001Bh001Ch Count Source Protect Mode Register CSPR00h10000000b(8) 001Dh001Eh001Fh0020h0021h0022h0023h High-Speed On-Chip Oscillator Control Register 0FRA000h0024h High-Speed On-Chip Oscillator Control Register 1FRA1Value when shipping 0025h High-Speed On-Chip Oscillator Control Register 2FRA200h0026h0030h0031h Voltage Detection Register 1(2)VCA100001000b 0032h Voltage Detection Register 2VCA200h(3)01000000b(4) 0033h0034h0035h0036h Voltage Monitor 1 Circuit Control Register VW1C0000X000b(3)0100X001b(4) 0037h Voltage Monitor 2 Circuit Control Register(5)VW2C00h0038h0039h003FhX: UndefinedNOTES:1.The blank regions are reserved.
