Multi-Point SupportSet only the speed for endpoint 0 because endpoint 0 only has the facilities to handle control transactions and there-fore is always associated with a device endpoint 0. Use bits 7–6 of the Type 0 register to set the speed. The register is located at address 0x1A when the index register is set to 0.Multi-Point OperationAfter allocating functions to endpoints and recording the operating speed of the target device, multi-point opera-tions can be configured. Most operations in a multi-point set-up are the same as for the equivalent actions where the core is attached to a single other device.However, more steps are required when:•The option of dynamically switching the allocation of functions to endpoints is taken (for example, to allow the support of a wider range of devices).•The control packets normally associated with endpoint 0 are handled through a different endpoint.If dynamic allocation is used, the program must monitor the current data toggle state associated with the endpoint and with each of the devices that are allocated to that endpoint. This knowledge allows the program to select the correct data toggle state when switching occurs between one device and the other. (This action is the programs re-sponsibility. The core cannot determine what data toggle state is expected when a function switches in and out of use.)The data toggle state can be switched from its current state by writing to the appropriate USB_EP[n]_TXCSR_H or USB_EP[n]_RXCSR_H register. This activity sets the data toggle write enable and data toggle bits that are included in the registers when the core is in host mode.Data toggle write enable and data toggle bits are also included in the USB_EP0_CSR[n]_H register. However, con-trol operations carried out through endpoint 0 of the core normally leave the data toggle in the expected state. Where control packets are handled through an endpoint other than endpoint 0, programs must prompt for each setup token to be sent. Programs must set the USB_EP[n]_TXCSR_H.SETUPPKT bit when the core operates in host mode, along with the USB_EP[n]_TXCSR_H.TXPKTRDY bit. If the USB_EP[n]_TXCSR_H.SETUPPKT bit is not set, an OUT token is sent.Use endpoint 0 of the USB controller to handle control packets for all of the devices attached to the controller, and to switch the allocation of this endpoint, as appropriate. Sending the correct token is ensured, as is ensuring that the data toggle is correctly set for this endpoint.Using a different endpoint for this function is possible, as described, but note the following:•The control function must be allocated to an Rx/Tx endpoint pair (with the same endpoint number).•The chosen endpoints must each be associated with FIFOs that can accommodate the packet size associated with EP0 transactions at the chosen operating speed. The size is a minimum of 8 bytes for low-speed or full-speed transactions but 64 bytes for high-speed transactions.Suspending and Resuming the ControllerSuspend or Resume by Inactivity on the USB Bus (L0 to L2 State) in Peripheral ModeThe following steps occur in this mode.1.Entry into suspend mode. When operating as a peripheral, the USB controller monitors activity on the USBand when no activity has occurred for 3 ms, the controller goes into suspend mode. If the USB_IRQ.SUSPEND interrupt has been enabled, the USB controller now generates an interrupt. The USB_IRQ.SUSPEND output also goes low (if enabled).The POWERDWN signal is also asserted to indicate that the application can stop USB_CLKIN to save power.POWERDWN then remains asserted until either power is removed from the bus (indicating that the device has been disconnected) or resume signaling or reset signaling is detected on the bus.2.When resume signaling occurs on the bus, the USB_CLKIN must be restarted, if necessary. The USB controllerthen automatically exits suspend mode. If the USB_IRQ.RESUME interrupt is enabled, the USB controller gen-erates an interrupt.3.Initiating a remote wake-up. T o initiate a remote wake-up while the controller is in suspend mode, set theUSB_POWER.RESUME bit=1. ( If USB_CLKIN has been stopped, it must be restarted before this write can oc-cur.) The software must leave then this bit set for approximately 10 ms (minimum of 2 ms, a maximum of 15 ms) before resetting it to 0. By this time the hub is driving resume signaling on the USB.NOTE:The USB_IRQ.RESUME interrupt is not generated when the software initiates a remote wake-up. Suspend or Resume by Inactivity on the USB Bus (L0 To L2 State) in Host Mode The following steps occur in this mode.1.Entry into suspend mode. When operating as a host, the USB controller can be prompted to go into suspendmode by setting the USB_POWER.SUSPEND bit. When this bit is set, the USB controller completes the current transaction then stops the transaction scheduler and frame counter. No further transactions start and no SOF packets are generated. If the USB_POWER.SUSEN bit is set, the UTMI+ PHY goes into low-power mode when the controller goes into suspend mode and stops USB_CLKIN.2.Sending resume signaling. When the application requires the controller to leave suspend mode, it clears theUSB_POWER.SUSPEND bit, sets the USB_POWER.RESUME bit, and leaves it set for 20 ms. While theUSB_POWER.RESUME bit is high, the controller generates resume signaling on the bus. After 20 ms, the pro-cessor core must clear the USB_POWER.RESUME bit, at which point the frame counter and transaction schedu-ler start.3.Responding to remote wake-up. If resume signaling is detected from the target while the USB controller is insuspend mode, the UTMI+ PHY is brought out of low-power mode and restarts USB_CLKIN. The controller then exits suspend mode and automatically sets the USB_POWER.RESUME bit to 1 to take over generating the resume signaling from the target. If the USB_IRQ.RESUME interrupt is enabled, the USB controller generates an interrupt.USB Event Control•When SRP signaling is detected (A device only)•When device disconnect is detected (host mode)•When a session ends (peripheral mode)•When a device connection is detected (host mode)•At start of frame (SOF)•When reset signaling is detected on USB (peripheral mode)•When babble is detected (host mode)•In suspend mode, when resume signaling is detected on USB•When suspend signaling is detected (peripheral mode)The software generates interrupts for the following VBUS control requests:•Drive VBUS greater than 4.4 V (default A device)•Stop driving VBUS•Start charging VBUS (peripheral mode)•Stop charging VBUS•Start discharging VBUS (peripheral mode)•Stop discharging VBUSInterrupt HandlingWhen interrupted with a USB interrupt, the processor core must read the interrupt status register to determine which endpoints have caused the interrupt and jump to the appropriate routine. If multiple endpoints have caused the interrupt, endpoint 0 must be serviced first, followed by the other endpoints. The USB Interrupt Service Rou-tine figure shows a flowchart for the USB interrupt service routine.。

The setpoint control input is applied to the VSET pin and has an operating range of 0.25 V to 1.4 V. The associated circuit determines the slope and intercept of the linear-in-dB measurement system; these are nominally 23 mV/dB and −60 dBm for a 50 Ω termination (−73 dBV) at 0.9 GHz. Further simplifying the application of the AD8315, the input resistance of the setpoint interface is over 100 MΩ, and the bias current is typically 0.5 μA.

The POR time for enhanced configuration devices canbe set to either 100 ms or 2 ms, depending on its PORSEL pin setting. If thePORSEL pin is connected to GND, the POR delay is 100 ms. If the PORSELpin is connected to V CC, the POR delay is 2 ms. During this time, theconfiguration device drives its OE pin low. This low signal delaysconfiguration because the OE pin is connected to the target device’snSTATUS pin.1When selecting a POR time, you need to ensure that the devicecompletes power-up before the enhanced configuration deviceexits POR. Altera recommends that you use a 12-ms POR timefor the Stratix II or Stratix II GX device, and use a 100-ms PORtime for the enhanced configuration device.When both devices complete POR, they release their open-drain OE ornSTATUS pin, which is then pulled high by a pull-up resistor. Once thedevice successfully exits POR, all user I/O pins continue to be tri-stated.If nIO_pullup is driven low during power-up and configuration, theuser I/O pins and dual-purpose I/O pins will have weak pull-upresistors, which are on (after POR) before and during configuration. IfnIO_pullup is driven high, the weak pull-up resistors are disabled.f The value of the weak pull-up resistors on the I/O pins that are on beforeand during configuration can be found in the Stratix II Device Handbookor the Stratix II GX Device Handbook.When the power supplies have reached the appropriate operatingvoltages, the target device senses the low-to-high transition on nCONFIGand initiates the configuration cycle. The configuration cycle consists ofthree stages: reset, configuration and initialization. While nCONFIG ornSTATUS are low, the device is in reset. The beginning of configurationcan be delayed by holding the nCONFIG or nSTATUS pin low.1V CCINT, V CCIO and V CCPD of the banks where the configurationand JTAG pins reside need to be fully powered to theappropriate voltage levels in order to begin the configurationprocess.When nCONFIG goes high, the device comes out of reset and releases thenSTATUS pin, which is pulled high by a pull-up resistor. Enhancedconfiguration devices have an optional internal pull-up resistor on the OEpin. This option is available in the Quartus II software from the Generaltab of the Device & Pin Options dialog box. If this internal pull-upresistor is not used, an external 10-k pull-up resistor on theOE-nSTATUS line is required. Once nSTATUS is released, the device isready to receive configuration data and the configuration stage begins.。

PORT Functional DescriptionPORT Architectural ConceptsThese sections describe in more detail how the PORT module connects externally to pins and internally to the MMR bus. Ports are named alphabetically beginning with A.•Internal Interfaces•External Interfaces•GPIO Functionality•Port Multiplexing ControlInternal InterfacesAll of the pin multiplexing, GPIO, and pin interrupt control block MMRs can be accessed through the MMR bus. There is no DMA support. Each of the pin interrupt (PINTx) modules has its own dedicated interrupt request out-put signal that connects directly to the system event controller (SEC).External InterfacesThe pin multiplexing hardware can be seen as a layer between the on-chip peripherals and the silicon pads connect-ing to the physical pins/balls or the package, as controlled by the PORT unit.GPIO FunctionalityBy default, the PORT sets every GPIO pin to input mode. The input drivers are not enabled, which avoids the need for unnecessary current sinks and external termination resistors on unused pins.Input ModeThe default mode of every GPIO pin after reset is input mode, but the input drivers are not enabled. T o enable GPIO input drivers, set the bits corresponding to the PORT pins in the appropriate input enable register (PORT_INEN). When enabled, a read from the PORT_DATA register returns the logical state of the input pins; how-ever, the input signal does not overwrite the state of the internal flip-flop used for providing output to the same pin. Only software can alter the state. If the input driver is enabled, a write to the PORT_DATA register can alter the state of the flip-flop, but the change cannot be read back.Output ModeAny GPIO pin can be configured for output mode. The GPIO output drivers are enabled by setting the bits corre-sponding to the PORT pins in the appropriate direction register. The PORT implements direction registers as a pair ADSP-BF70x Blackfin+ Processor Hardware ReferencePORT Programming Model briefly describe the function of the different settings for each of the pin functions in the input, output, and open-drain GPIO modes. It is a best practice to use the SET or CLR versions of the PORT registers, where appicable, toeffect changes on a pin-by-pin basis rather than on the full port.For more detailed descriptions of the configurations, see PORT Register Descriptions.For output mode, first clear the PORT_DATA register to set all the pins low. Then write the PORT_DIR register to define the direction of each pin (set the bits associated with the desired output pins to 1). In output mode, the other registers are not significant. The GPIO Programming Model Flow (Part 1) chart shows this flow starting at label 2.Figure 20-2: GPIO Programming Model Flow (Part 1)For input mode, first decide the polarity for each pin using the PORT_POL register. Program the PORT_DIR register to define the appropriate pins as inputs (write a 0 to the bit location associated with the pin). If interrupts are de-sired, configure the PINT module as shown in the GPIO Programming Model Flow (Part 3) figure starting at label B.Finally, write the PORT_INEN register to enable the associated input drivers. The GPIO Programming Model Flow (Part 2) chart shows this entire flow starting at label 3.For open-drain mode, set all pins low by clearing the PORT_DATA register. Then, use the PORT_INEN register to enable the appropriate input drivers. Set the PORT_DIR register in this mode to indicate whether the pin is in an active state or not (active being 0). The GPIO Programming Model Flow (Part 2) chart shows this flow starting at label 4.ADSP-BF70x Blackfin+ Processor Hardware ReferencePort x GPIO Data RegisterThe operation of the PORT_DATA register depends on whether the bit/pin is in output mode or input mode. In both modes, a set bit in the PORT_DATA register corresponds to a signal high on a GPIO pin. A cleared bit in the PORT_DATA register corresponds to a signal low on a GPIO pin.The PORT_DATA , PORT_DATA_SET , and PORT_DATA_CLR registers control the state of GPIO pins in output mode. To enable output mode (and output drivers), use the PORT_DIR_SET and PORT_DIR_CLR registers.Writes to the PORT_DATA register affect the state of all pins of the port that are in output mode. To set or clear specific pins without impacting other pins of the port, use the PORT_DATA_SET and PORT_DATA_CLR registers.When the GPIO pins are in input mode (input driver is enabled with the PORT_INEN register), reads from the PORT_DATA , PORT_DATA_SET , and PORT_DATA_CLR registers return the state of the respective GPIO pins.Note that when the input driver is not enabled, reads from the PORT_DATA , PORT_DATA_SET , and PORT_DATA_CLR registers return the value previously written to the registers.Port x Bit 7 DataPort x Bit 8 DataPort x Bit 6 Data Port x Bit 9 DataPort x Bit 5 Data Port x Bit 10 DataPort x Bit 4 Data Port x Bit 11 DataPort x Bit 3 Data Port x Bit 12 DataPort x Bit 2 Data Port x Bit 13 DataPort x Bit 1 Data Port x Bit 14 DataPort x Bit 0 DataPort x Bit 15 DataPX7 (R/W)PX8 (R/W)PX6 (R/W)PX9 (R/W)PX5 (R/W)PX10 (R/W)PX4 (R/W)PX11 (R/W)PX3 (R/W)PX12 (R/W)PX2 (R/W)PX13 (R/W)PX1 (R/W)PX14 (R/W)PX0 (R/W)PX15 (R/W)1501401301201101009080706050403020100Figure 20-5: PORT_DATA Register DiagramADSP-BF70x PORT Register DescriptionsADSP-BF70x Blackfin+ Processor Hardware Reference。

Pixel Compositor image, one could setup a 2D-DMA to only bring in the area of the main image that is affected by the overlay. This may reduce the amount ofDMA activity thus potentially improving system performance.There are two steps to implement the overlay process:1.Defining an overlay buffer•The user must define a rectangular region that covers thewhole overlay region no matter what shape the overlay con-tent is. The overlay buffer holds the pixel data in the entirerectangular overlay region, which can include some areaswhere there is no overlay. In memory, these areas have to befilled with the transparent color value. (See “TransparencyControl” on page28-17.)2.Configuring the overlay DMA•The user must define a single DMA descriptor for the over-lay data transfer. The user must also fill the overlaycoordinate registers in the PIXC with appropriate values.The overlay coordinate register set consists of two pairs ofregisters that specify the top left corner (H-Start, V-Start)and bottom right corner (H-End, V-End) of the overlay,along with a 4-bit register that specifies the (transparencyratio) value. Each overlay is thus completely specified by aset of five registers. The widths and addresses of these regis-ters are given in “PIXC Registers” on page28-35.There is a set of an additional five such registers that can be used to specifya second overlay region, so that two separate overlay blocks can be definedsimultaneously. Furthermore, either or both of these overlay coordinate register sets can be enabled or disabled at one time, since separate enable bits (OVR_A_EN and OVR_B_EN) exist in the PIXC control register for each of the overlay register sets.ADSP-BF54x Blackfin Processor Hardware ReferenceADSP-BF54x Blackfin Processor Hardware ReferencePixel CompositorTransparent ColorA transparent color is a specific color that is removed from one image to reveal another “behind” it. This technique is also referred to as chroma keying. The principal subject is photographed or filmed against a back-ground having a single color, usually in the blue or green spectrums.When the phase of the chroma signal corresponds to the pre-programmed state associated with the background color(s) behind the principal subject, the signal from the alternate background (which in this case comes from the main image channel) is inserted in the composite signal and presented at the output. When the phase of the chroma signal deviates from that associated with the background color(s) behind the principal subject, the picture data associated with the principal subject (in this case, the overlay image) is presented at the output. Figure 28-10 illustrates this concept.In order to display the main image in the two triangle areas ∆ABE and ∆CDE in overlay block ABCD, the data in the overlay buffer correspond-ing to the pixels in the triangle areas ∆ABE and ∆CDE must hold a specific value, called the transparent color.Figure 28-10.

Memory read that occurs in the program source code after a write in the program flow to actually return its value before the write is completed. This order-ing provides significant performance advantages in the operation of most memory instructions. However, it can cause side effects that the program-mer must be aware of to avoid improper system operation.When writing to or reading from non memory locations such as I/Odevice registers, the order of how read and write operations complete is often significant. For example, a read of a status register may depend on a write to a control register. If the address is the same, the read would returna value from the write buffer rather than from the actual I/O device regis-ter, and the order of the read and write at the register may be reversed.Both these effects could cause undesirable side effects in the intendedoperation of the program and peripheral. To ensure that these effects do not occur in code that requires precise (strong) ordering of load and store operations, synchronization instructions (CSYNC or SSYNC) should be used. Synchronizing InstructionsWhen strong ordering of loads and stores is required, as may be the case for sequential writes to an I/O device for setup and control, use the core or system synchronization instructions, CSYNC or SSYNC, respectively.The CSYNC instruction ensures all pending core operations have completed and the core buffer (between the processor core and the L1 memories) is flushed before proceeding to the next instruction. Pending core operations may include any pending interrupts, speculative states (such as branch predictions), or exceptions.Consider the following example code sequence:IF CC JUMP away_from_herecsync;r0 = [p0];away_from_here:ADSP-BF54x Blackfin Processor Hardware ReferenceADSP-BF54x Blackfin Processor Hardware ReferenceSystem Reset and BootingIn flash mode all the muxed address lines (A4 to A9 on port H andA10 to A25 on port I) are activated by the boot kernel. When BMODE = 0001, none of these pins can function as an input without exter-nal hardware protection. Upper address pins are unlikely to toggle and can still be used for GPIO output purposes, with the limita-tion that the pins are driven low during boot time.When the EBIU registers are configured to burst-flash mode by the pre-boot due to OTP programming, the boot kernel activates the NOR clock on the PI15 pin rather than the A25 line.After RESET has released, the preboot processes a number of OTP pages. Then, the boot kernel starts reading data from the external flash memory. The initial cycles of the flash boot are shown in Figure 17-14.
