Most Li-Ion and Li-Po cells exceed 3.6 V when fully charged2When using the provided interfaces with add-on boards or other external hardware, tighter voltage limits might apply2.2 Current ConsumptionThe operating current of the board greatly depends on the application and the amount of external hardware connected. The table below attempts to give some indication of typical current consumptions for the EFM8BB52 and the on-board debugger. Note that the numbers are taken from the data sheets for the devices. For a full overview of the conditions that apply for a specific number from a data sheet, the reader is encouraged to read the specific data sheet.Table 2.1. Current Consumption1From EFM8BB52 data sheet2From EFM32GG12 data sheet3. HardwareThe core of the BB52 Explorer Kit is the EFM8BB52 Busy Bee 8-bit microcontroller. Refer to section 1.4 Kit Hardware Layout for place-ment and layout of the hardware components.3.1 Block DiagramAn overview of the BB52 Explorer Kit is illustrated in the figure below.ExpandabilityDebuggingEFM8BB52Temperature & Humidity Sensor Ambient Light & UV SensorHall Effect Sensor Qwiic Connector mikroBUS SocketFigure 3.1. Kit Block Diagram3.2 Power SupplyThe kit is powered by the debug USB cable as illustrated in the figure below.AutomaticIsolationPeripheralsEFM8BB528-bit MCUPeripheralsFigure 3.2. BB52 Explorer Kit Power TopologyThe 5 volt power net on the USB bus is regulated down to 3.3 V using an LDO (low-dropout regulator). An automatic isolation circuit isolates the LDO when the USB cable is not plugged in.Power can be injected externally on the VMCU net if the USB cable is removed and no other power sources are present on the kit. Failure to follow this guideline can cause power conflicts and damage the LDO.3.3 EFM8BB52 ResetThe EFM8BB52 can be reset by a few different sources:• A user pressing the RESET button.•The on-board debugger pulling the #RESET pin low.3.4 Push Button and LEDThe kit has one user push button, marked BTN0, that is connected to a GPIO on the EFM8BB52. The button is connected to pin P0.2 and it is debounced by an RC filter with a time constant of 1 ms. The logic state of the button is high while the button is not being pressed, and low when the button is pressed.The kit also features one yellow LED, marked LED0, that is controlled by a GPIO pin on the EFM8BB52. The LED is connected to pin P1.4 in an active-high configuration.Button & LEDFigure 3.3. Button and LED3.5 On-board DebuggerThe BB52 Explorer Kit contains a microcontroller separate from the EFM8BB52 Busy Bee that provides the user with an on-board J-Link debugger through the USB Micro-B port. This microcontroller is referred to as the "on-board debugger", and is not programmable by the user. When the USB cable is removed, the on-board debugger goes into a very low power shutoff mode (EM4S).In addition to providing code download and debug features, the on-board debugger also presents a virtual COM port for general pur-pose application serial data transfer.The figure below shows the connections between the target EFM8BB52 device and the on-board debugger. The figure also shows the presence of the Mini Simplicity Connector, and how this is connected to the same I/O pins.Please refer to chapter 4. Debugging for more details on debugging.Mini Simplicity ConnectorP0.5 (UARTx.RX)Figure 3.4. On-Board Debugger Connections3.6 ConnectorsThe BB52 Explorer Kit features a USB Micro-B connector, breakout pads, a mikroBUS connector for connecting mikroBUS add-on boards, and a Qwiic connector for connecting Qwiic Connect System hardware. The connectors are placed on the top side of the board,and their placement and pinout are shown in the figure below.

BB52 Explorer Kit Connectors3.6.1 Breakout Pads34 breakout pads are provided and allow connection of external peripherals. The breakout pads are arranged in two rows and contain a number of I/O pins that can be used with most of the EFM8BB52 Busy Bee's features. Additionally, the VMCU (main board power rail), 3V3 (LDO regulator output), and 5V power rails are also exposed on the pads.The pin-routing on the Busy Bee is flexible, so most peripherals can be routed to any pin on port 1 or 2. However, pins may be shared between the breakout pads and other functions on the BB52 Explorer Kit. The figure in section 3.6 Connectors includes an overview of the breakout pads and functionality that is shared with the kit.3.6.2 MikroBUS SocketThe BB52 Explorer Kit features a mikroBUS™ socket compatible with mikroBUS add-on boards. MikroBUS add-on boards can expand the functionality of the kit with peripherals such as sensors and LCDs. Add-on boards follow the mikroBUS socket pin mapping, and communicates with the on-kit EFM8BB52 through UART, SPI or I2C. Several GPIOs are exposed on the mikroBUS socket. MikroBUS add-on boards can be powered by the 5V or VMCU power rails, which are available on the mikroBUS socket.The pinout of the EFM8BB52 on the kit is made such that all required peripherals are available on the mikroBUS socket. The I2C sig-nals are, however, shared with the Qwiic connector, and all mikroBUS signals are also routed to adjacent breakout pads.When inserting a mikroBUS add-on board, refer to the orientation notch on the BB52 Explorer Kit, shown in the figure below, to ensure correct orientation. Add-on boards have a similar notch that needs to be lined up with the one shown below.socketFigure 3.6. mikroBUS Add-on Board OrientationThe table below gives an overview of the mikroBUS socket pin connections to the EFM8BB52.Table 3.1. mikroBUS Socket Pinout3.6.3 Qwiic ConnectorThe BB52 Explorer Kit features a Qwiic® connector compatible with Qwiic Connect System hardware. The Qwiic connector provides an easy way to expand the functionality of the BB52 Explorer Kit with sensors, LCDs, and other peripherals over the I2C interface. The Qwiic connector is a 4-pin polarized JST connector, which ensures the cable is inserted the right way.Qwiic Connect System hardware is daisy chain-able as long as each I2C device in the chain has a unique I2C address.Note: The Qwiic I2C connections on the BB52 Explorer Kit are shared with the mikroBUS I2C signals.The Qwiic connector and its connections to Qwiic cables and the EFM8BB52 are illustrated in the figure below.Qwiic cableGNDVMCUSDA - P1.5SCL - P1.6Figure 3.7. Qwiic ConnectorThe table below gives an overview of the Qwiic connections to the EFM8BB52.Table 3.2. Qwiic Connector Pinout3.6.4 Debug USB Micro-B ConnectorThe debug USB port can be used for uploading code, debugging, and as a virtual COM port. More information is available in section 4. Debugging.4. DebuggingThe BB52 Explorer Kit contains an on-board SEGGER J-Link Debugger that is connected to the C2 debugging interface on the EFM8BB52. The debugger allows the user to download code and debug applications running in the target EFM8BB52. Additionally, it also provides a virtual COM port (VCOM) to the host computer that is connected to the target device's serial port, for general purpose communication between the running application and the host computer. The on-board debugger is accessible through the USB Micro-B connector.4.1 On-board DebuggerThe on-board debugger is a SEGGER J-Link debugger running on an EFM32 Giant Gecko. The debugger is directly connected to the debug and VCOM pins of the target EFM8BB52.When the debug USB cable is inserted, the on-board debugger is automatically active, and takes control of the debug and VCOM inter-faces. This means that debug and communication will not work with an external debugger connected at the same time. The on-board LDO is also activated, providing power to the board.When the USB cable is removed, the board might still be running on external power, as described in section 3.2 Power Supply. In this case, the on-board debugger goes into a very low power shutoff mode (EM4S), consuming about 80 nA.4.2 Virtual COM PortThe virtual COM port is a connection to a UART of the target EFM8BB52 and allows serial data to be sent and received from the de-vice. The on-board debugger presents this as a virtual COM port on the host computer that shows up when the USB cable is inserted.Data is transferred between the host computer and the debugger through the USB connection, which emulates a serial port using the USB Communication Device Class (CDC). From the debugger, the data is passed on to the target device through a physical UART connection.The serial format is 115200 bps, 8 bits, no parity, and 1 stop bit by default.Note: Changing the baud rate for the COM port on the PC side does not influence the UART baud rate between the debugger and the target device.Schematics, Assembly Drawings, and BOM 5. Schematics, Assembly Drawings, and BOMSchematics, assembly drawings, and bill of materials (BOM) are available through Simplicity Studio when the kit documentation pack-age has been installed.

STM8 Bootloader
自制Stm8 bootloader由于本人项目需要，要做STM8L052R8的bootloader，用于远程程序升级功能，为了安全考虑，不使用ST自带的bootloader，而是自制bootloader。
基本的功能是这样的，首先程序运行在一个V1.0的版本上，且带了BOOT，当程序收到一条命令后，程序跑入死循环，等待硬件看门狗复位；程序复位后进入bootload区，等待第二条命令的接收，接收到正确的数据帧后，bootloader开始擦除FLASH，并接收数据包，直到最后一个数据包接收完毕，通过指示灯以2HZ的频率闪烁，指示升级完成。
第一步：boot区程序设计，首先修改link文件，define region NearFuncCode = [from 0x8000 to 0xAFFF];define region FarFuncCode = [from 0x8000 to 0xAFFF];define region HugeFuncCode = [from 0x8000 to 0xAFFF];place at start of NearFuncCode { block INTVEC };以上是link文件部分，可以看出flash地址为0x8000开始，结束于0x17FFF; 长度为64kB,中断向量地址为0x8000,这样，知道了这个我们就可以修改BOOT程序的link和主程序的link了,这里我把BOOTLOAD区划分为8K,应用区为48K设置link文件如下，这样把boot区和APP区分开，互不干扰，你也可以根据需要调整他们的大小。
program:define region NearFuncCode = [from 0xB000 to 0xFFFF];define region FarFuncCode = [from 0xB000 to 0xFFFF]| [from 0x10000 to0x17FFF];define region HugeFuncCode = [from 0xB000 to 0x17FFF];place at start of NearFuncCode { block INTVEC };bootload:define region NearFuncCode = [from 0x8000 to 0xAFFF];define region FarFuncCode = [from 0x8000 to 0xAFFF];define region HugeFuncCode = [from 0x8000 to 0xAFFF];place at start of NearFuncCode { block INTVEC };像STM32这样的芯片中断向量地址可以任意定，所有boot区和APP区都可以使用中断，且互不干扰，但是STM8的中断向量表固定在0X8000地址，不能修改，所以BOOT 区不能开中断，否则会和APP区的中断打架，但是APP区的一但开启中断后就会跳转到0x8000地址，这样就跳到了BOOT区，因此需要使用跳转指令将中断跳回到APP区，__root const long reintvec[]@".intvec"={ 0x82008080,0x8200b004,0x8200b008,0x8200b00c, //当应用程序地址不是0xB000时则要相应改掉除第一个0x8200b010,0x8200b014,0x8200b018,0x8200b01c, //0x82008080以外的数值0x8200b020,0x8200b024,0x8200b028,0x8200b02c,0x8200b030,0x8200b034,0x8200b038,0x8200b03c,0x8200b040,0x8200b044,0x8200b048,0x8200b04c,0x8200b050,0x8200b054,0x8200b058,0x8200b05c,0x8200b060,0x8200b064,0x8200b068,0x8200b06c,0x8200b070,0x8200b074,0x8200b078,0x8200b07c,};这里大概的含义就是重定义STM8的中断，STM8中断向量重定义，至于这里为什么这样写，请网上自己去看，我也不是很清楚。

The buttons are connected to pins P0.2 and P0.3.In addition to the two push buttons, the kit also features a tri-color LED that is controlled by EFM8 GPIO. The LED is connected to pins P1.6, P1.7, and P2.0 in an active-low configuration.Figure 5.1. Buttons/LEDs5.2 JoystickThe kit has an analog joystick with 8 measureable positions. This joystick is connected to the EFM8 on the P2.5 pin and uses different resistor values to create voltages measurable by the ADC0.Figure 5.2. JoystickTable 5.1. Joystick Resistor Combinations5.3 Memory LCD-TFT DisplayA 1.28-inch SHARP Memory LCD-TFT has been added to the board to enable interactive applications to be developed. The display has a high resolution of 128 by 128 pixels and consumes very little power. It is a reflective monochrome display, so each pixel can only be light or dark, and no backlight is needed in normal daylight conditions.The display interface consists of an SPI-compatible serial interface and some extra control signals. Data are sent to the display one line (128 bits) at a time.The Memory LCD-TFT display is shared with the kit Board Controller, allowing the Board Controller application to display useful infor-mation when the user application is not using the display. The EFM8 MCU always controls ownership of the display using the EFM_DISP_ENABLE signal:•0: The Board Controller has control of the display.•1: The user application (EFM8) has control of the display.Data are clocked in on EFM_DISP_MOSI (P1.0) when EFM_DISP_CS (P0.1) is high, and the clock is sent on EFM_DISP_SCLK (P0.6). The maximum supported clock speed is 1 MHz.Please refer to the display application information for details on driving the display:/1-28-inch-memory-lcd.html8Figure 5.3. 128x128 Pixel Memory LCD5.4 USB Micro-B ConnectorThe EFM8UB2-SLSTK2001A board is equipped with a USB Micro-B connector supporting device USB. The figure below shows how the USB lines are connected to the MCU.Figure 5.4. EFM8 USB Connector6. Connectors6.1 Breakout PadsMany of the EFM8's pins are routed out to "breakout pads" at the top and bottom edges of the kit. A 2.54 mm pitch pin header can be soldered in for easy access to these pins. Most I/O pins are available, with the exception of pins used to drive the LCD.Note: Some of the breakout pads are shared by on-board EFM peripherals. The schematic must be consulted to make sure that it is acceptable to use a shared pin in your application.P 0.0P 0.1P 0.2P 0.3P 0.5P 0.60.7P 1.0P 1.1P 1.2P 1.3P 0.4P 2.7P 2.6P 2.5P 2.4P 2.2P 2.1P 2.0P 1.7P 1.6P 1.5P 1.4P 2.3P 4.7P 4.6P 4.5P 4.4P 3.0P 3.1P 3.2P 3.3P 3.5P 3.6P 3.7P 4.0P 4.1P 4.2P 4.3P 3.4V M C UV M C U Figure 6.1. Breakout Pads and Expansion Header6.2 Expansion HeaderOn the right hand side of the board an angled 20-pin expansion header is provided to allow connection of peripherals or plugin boards. The connecter contains a number of I/O pins that can be used with most of the EFM8UB2 Universal Bee's features. Additionally, the VMCU, 3V3 and 5V power rails are also exported.The figure below shows the pin assignment of the expansion header. With the exception of a few pins, most of the expansion header's pins are the same as those on the EFM32 Gecko or EFM32 Tiny Gecko starter kits.Figure 6.2. Expansion HeaderSome of the chip peripheral functions that are available on the expansion header are listed in the table below.Table 6.1. Some Peripheral Functions Available on Expansion HeaderNote: This table only sums up some of the alternate functions available on the expansion header. Consult the EFM8UB20F64G data sheet for a complete list of alternate functions.6.3 Debug ConnectorThis connector is used for Debug In and Debug Out (see chapter on Debugging).Figure 6.3. Debug ConnectorTable 6.2. Debug Connector Pinout6.4 Direct Debug ConnectorThis connector (J103) is used for directly debugging the EFM8 using an external debug adapter (see chapter on Debugging). This is especially useful for debugging the MCU on the STK board when the part is battery powered or powered by an external supply.Figure 6.4. Direct Debug ConnectorTable 6.3. Direct Debug Connector Pinout6.5 Reference BoardThe top-right corner of the board includes a 20-pin reference board connector. The connecter contains some I/O pins that can be used with some of the EFM8 EFM8UB2 Universal Bee's features. Additionally, the 3V3 and 5V power rails are also exported.The figure below shows the pin assignment of the reference board header.Figure 6.5. Reference Board Header7. Integrated Development EnvironmentFigure 7.1. Simplicity StudioSimplicity Studio includes various examples in source form to use with the Starter Kit. To run these examples:1.Provide power to the board by connecting the DBG USB connector to the PC using the provided USB cable.2.Move the switch to the AEM position.3.Select the J-Link adapter for the kit under [Devices ].4.Click the [Getting Started ]>[New Project ] button.5.In the wizard, ensure the EFM8UB2 Universal Bee Starter Kit Board kit and click [Next ].6.Select [Example ] and click [Next ].7.Select the desired example or demo from the list and click [Next ].8.Click [Finish ].9.Click the [Debug ] button in the IDE to build and download the code to the hardware.10.Follow the instructions at the top of the main example file to set up the hardware as needed.11.Click the [Resume ] button to start running the example.Integrated Development Environment8. Advanced Energy MonitorWhen the EFM8UB2 Starter Kit is connected to a Silicon Labs STK, the STK's Advanced Energy Monitor (AEM) hardware also meas-ures the slstk2001a power consumption using the VMCU connection on the EXP header. By using the [Energy Profiler] in Simplicity Studio, current consumption and voltage can be measured in real time.More details about AEM and its operation can be found in the STK User Guide. Note that AEM will measure the current for all circuitry connected to VMCU, including the STK MCU and the CPT device.Figure 8.1. Measuring EFM8UB2-SLSTK2001A Current Using AEM8.1 UsageThe AEM data is collected by the board controller and can be displayed by the energyAware Profiler, available through Simplicity Stu-dio. By using the energyAware Profiler, current consumption and voltage can be measured in realtime.8.2 AEM Theory of OperationIn order to be able to accurately measure current ranging from 0.1 µA to 50 mA (114 dB dynamic range), a current sense amplifier is utilized together with a dual gain stage. The current sense amplifier measures the voltage drop over a small series resistor, and the gain stage further amplifies this voltage with two different gain settings to obtain two current ranges. The transition between these two ranges occurs around 250 µA. Digital filtering and averaging is done within the Board Controller before the samples are exported to the Energy Profiler application.During startup of the kit, an automatic calibration of the AEM is performed. This calibration compensates for the offset error in the sense amplifiers.Figure 8.2. Advanced Energy Monitor8.3 AEM Accuracy and PerformanceThe AEM is capable of measuring currents in the range of 0.1 µA to 50 mA. For currents above 250 µA, the AEM is accurate within 0.1 mA. When measuring currents below 250 µA, the accuracy increases to 1 µA. Even though the absolute accuracy is 1 µA in the sub 250 µA range, the AEM is able to detect changes in the current consumption as small as 100 nA. The AEM produces 6250 current samples per second.Note: The current measurement will only be correct when powering the EFM8 from USB power through the debugger (power select switch set to DBG or AEM).Board Controller 9. Board ControllerThe kit contains a board controller that is responsible for performing various board-level tasks, such as handling the debugger and the Advanced Energy Monitor. An interface is provided between the EFM8 and the board controller in the form of a UART connection. The connection is enabled by setting the EFM_BC_EN (P0.0) line high, and using the lines EFM_BC_TX (P0.4) and EFM_BC_RX (P0.5) for communicating.The BC enable signal connects the EFM8 to the board controller:•0: EFM8 UART pins are isolated from the Board Controller.•1: EFM8 UART pins are connected to the Board Controller (default upon reset).Note: The board controller is only available when USB power is connected.Debugging 10. DebuggingThe EFM8UB2-SLSTK2001A contains an integrated debugger, which can be used to download code and debug the EFM8UB2 Univer-sal Bee EFM8 MCU. In addition to programming the MCU on the kit, the debugger can also be used to program and debug external Silicon Labs EFM8 devices.10.1 Debug ModesProgramming external devices is done by connecting to a target board through the provided Debug IN/OUT Connector, and by setting the debug mode to [Out]. The same connector can also be used to connect an external debugger to the EFM8 MCU on the kit, by setting the debug mode to [In]. A summary of the different supported debug modes is given in Table 10.1 Debug Modes on page 19.Table 10.1. Debug ModesSelecting the active debug mode is done with a drop-down menu in the Kit Manager tool, which is available through Simplicity Studio. When using the debug adapter in the [Out] mode, the end device must be manually detected before debugging and programming. To do this:1.Right-click on the kit from the Simplicity Studio launch screen and select [Select Target Part...].2.If needed, select the appropriate [Target Interface] for the external device. For example, EFM8 devices will use the [C2] selection.3.In the same dialog, click the [Detect Target] button.4.Click [OK] to close the dialog. The external target can now be debugged and programmed.10.2 Debugging during Battery OperationWhen the EFM8 is powered by battery and the J-Link USB is still connected, the on-board debug functionality is available. If the USB power is disconnected, the Debug In mode will stop working.To enable debugging when the USB cable is removed, connect an external debugger to the MCU Debug Header in the top right corner of the EFM8UB2-SLSTK2001A instead of the Debug IN/OUT Connector. This header is connected directly to the EFM8's debug inter-face. The pinout of this header is shown in the Connectors chapter.Upgrading the Kit 11. Upgrading the KitUpgrading the kit firmware is done through Simplicity Studio in the [Launcher] perspective. Simplicity Studio will automatically check for new updates on startup. After selecting a kit in the left under [Devices], the area at the top of the Launcher page displays the current kit version and Debug Mode. Use the links in this area to change the debug mode or upgrade the kit firmware.Schematics, Assembly Drawings, and BOM 12. Schematics, Assembly Drawings, and BOMThe schematics, assembly drawings and bill of materials (BOM) for the EFM8UB2 Starter Kit board are available through Simplicity Studio when the kit documentation package has been installed.12.1 Board Revision History•A00 — Initial revision for production.•A01 — Changed ESD protection diode for the EFM8's USB.•A02 — Removed R820 and added C113 0.1 µF.A00 Revision BoardsThere are no known issues with the A00 boards.A01 Revision BoardsThere are no known issues with the A01 boards.A02 Revision BoardsThere are no known issues with the A02 boards.Revision History 13.

注意：请注意，bootload记录是由hex2boot.exe主机端工具创建的。
有关此工具的更多信息，请参见5.使用主机端工具。
4.功能概述4.1系统架构如下图所示，EFM8引导加载程序工具将读取一个映像文件（十六进制或二进制），并将其转换为一系列引导程序2命令。
这些命令格式化为引导记录，存储在文件中或直接发送到EFM8设备。
使用相同的二进制记录格式，无论是保存到文件还是通过引导加载程序传输。
引导程序命令被设计为不返回任何数据，并且它们包含执行命令所需的所有信息并确定成功或失败。
要实现嵌入式主机，请从文件读取每个记录，将其发送到EFM8设备，并等待确认。
因为引导记录文件是二进制的，所以它对图像增加了很少的开销，应该很容易嵌入。
4.2引导程序概述所有设备都使用UART（〜500字节），SMBus（〜500字节）或USB HID（〜1.5 kB）引导加载程序进行预编程。
这个引导程序驻留在代码安全页面中。
如果它太大，不适合代码安全页面，它也将占用最后一页代码闪存。
它可以擦除如果不需要。
锁定字节之前的字节是Bootloader签名字节。
将此字节设置为值0xA5表示引导加载程序的存在在系统中。
此位置中的任何其他值表示引导加载程序不存在于闪存中。
当存在引导加载程序时，设备将在任何重置后跳转到引导加载程序向量，从而允许引导程序运行。
引导程序然后确定设备是否应保持在引导加载模式或跳转到位于0x0000的复位向量。
当bootloader不存在，任何复位后，器件将跳转到0x0000的复位向量。
4.3引导加载程序功能特性本节讨论引导程序固件的特定功能。
请注意，引导加载程序源代码和预构建的十六进制文件可在Simplicity Studio中使用[Software Examples]图块或可用在Silicon Labs网站（https:///8bit-appnotes）上。
这使Bootloader可以在任何设备上进行重新编程如果意外删除，并且可以根据需要为任何应用程序定制引导程序。
AN945：EFM8 Factory Bootloader用户指南功能概述SILABS。
4.3.1进入引导加载模式•在任何复位时，如果闪存地址0x0000为0xFF（即，未编程复位向量的第一个字节），引导加载程序将启动。
这个确保新的或已擦除的部件启动引导程序进行生产编程。
为了强壮，Bootloader将首先擦除Flash页面0，最后写入闪存地址0x0000。
这样可以确保任何中断引导加载操作将在中断擦除结束重新启动。
•要根据需要启动引导加载程序，应用程序固件可以在Bank 0（数据地址0x00）的R0中设置签名值0xA5，然后启动设备的软件复位。
如果引导加载程序使用R0中的签名值看到软件复位，则它将启动引导程序执行而不是跳转到应用程序。
•为了在应用程序损坏的情况下提供故障安全操作，引导加载程序将在上电复位（POR）或引脚复位时启动如果引脚保持低电平超过50μs。
表4.1总结中提供了每个设备和包的入口引脚的完整列表引导加载模式条目的引脚第10页。
此引导加载程序输入法的引脚也可以通过查看efm8_device.h文件中的bootloader源代码。
没有选项禁用此条目方法。
4.3.1.1Rainbow Blinky示例[Demo]文件夹中的[Rainbow Blinky]（或EFM8SB1的[PWM Blinky]）示例可以使用[Software Examples] Simplicity Studio演示如何使用软件重置条目方法创建可以进入引导加载模式的应用程序。
除了标准的Rainbow Blinky操作之外，本应用程序还查看入门工具包上的PB0是否被按下。
如果是，那么示例在LCD屏幕上显示[Loader]，将0xA5的签名值写入R0地址（数据地址0x00），并启动软件重置。
当这种情况发生时，引导加载程序会看到数据地址的签名值，并保持在引导加载模式。
该这样做的代码很简单，如下所示：// Start the bootloader if PB0 is pressedif (BSP_PB0 == BSP_PB_PRESSED){// Print "Loader" to the screencolorIndex = 8;DrawColorName();// Write R0 and issue a software reset*((uint8_t SI_SEG_DATA *)0x00) = 0xA5;RSTSRC = RSTSRC_SWRSF__SET | RSTSRC_PORSF__SET;}4.3.2通讯接口•引导加载程序通信接口被轮询，因为引导加载程序无法访问第0页的中断向量。
