翻译The Write Status Register instruction allows the Status Registers to be written. The writable Status Register bits include: SRP, TB, BP[3:0] in Status Register-1; CMP, LB[3:1], QE, SRL in Status Register-2;HOLD/RST, DRV1, DRV0, WPS & ADP in Status Register-3. All other Status Register bit locations are read-only and will not be affected by the Write Status Register instruction. LB[3:1] are non-volatile OTP bits, once it is set to 1, it cannot be cleared to 0.

写入状态寄存器指令允许对状态寄存器进行写入操作。可写的状态寄存器位包括:在状态寄存器1中的SRP,TB,BP [3:0];在状态寄存器2中的CMP,LB [3:1],QE,SRL;在状态寄存器3中的HOLD/RST,DRV1,DRV0,WPS和ADP。所有其他状态寄存器位位置均为只读,不会受到写入状态寄存器指令的影响。LB [3:1]是非易失性的OTP位,一旦设置为1,就无法清除为0。

引用[1]:这个错误是由于在代码中使用了不兼容的指令导致的。根据引用中的描述,可以尝试将代码中的__CC_ARM宏定义去掉,然后重新编译。这样应该可以解决这个错误。引用[2]:根据引用中的描述,这个问题是关于STM32F103C8T6最小系统版的PC13引脚的LED灯的使用。在STM32CubeMX中,将该引脚设置为output模式,并在任务函数中添加代码来控制LED灯的翻转和延时。引用[3]:根据引用中的描述,这个问题是关于使用STM32CubeMX配置FreeRTOS的过程。首先需要选择对应的芯片,并配置系统时钟源和晶振。然后在Middleware中选择FreeRTOS,并设置任务和队列。最后生成工程代码并进行编译。如果出现报错,可以尝试根据引用中的描述进行调整,例如更换编译器版本或替换源代码文件。
Describe the execution of the JMP instruction if R3 contains x369C (refer to Example 4.5). (6 points)
Without information about the specific architecture and instruction set being used, it is difficult to provide a definitive answer. However, in general, the JMP instruction is typically used to change the flow of execution to a different memory location or address.
In Example 4.5, R3 contains the value x369C. Depending on the specific instruction set being used, this could represent a memory address that the JMP instruction would jump to. For example, if the instruction set uses a direct addressing mode, the JMP instruction might load the program counter with the value in R3, causing the processor to begin executing instructions at memory address x369C.
Alternatively, if the instruction set uses a relative addressing mode, the JMP instruction might add the value in R3 to the current program counter value to determine the new address to jump to. For example, if the current program counter is x2000 and R3 contains x369C, the JMP instruction might cause the program counter to be set to x569C.
Ultimately, the exact behavior of the JMP instruction will depend on the specific architecture and instruction set being used.
