Web描述中提到，对afio_evcr，afio_mapr，afio_exticrx读写前要先打开afio时钟，那在本次实例中，我们究竟需不需要对这3个寄存器进行读写操作呢？ 由于AFIO_EVCR是事件控制寄存器，AFIO_EXTICRX是外部中断控制寄存器，这两个在本次实例中我们都用不到，因此我们重点来看AFIO ... WebThis first sets AFIO_MAPR to 0x02000000 to disable the JTAG pins. Then, while remapping TIM4 it sets AFIO_MAPR to 0x04001000 which both remaps TIM4 and completely disables JTAG and SWD. This happens because the undefined read of the SWJ_CFG bits gets written back to the AFIO_MAPR. WebSep 2, 2024 · AFIO: Alternate function I/O and debug configuration. To optimize the number of peripherals available for the 64-pin or the 100-pin or the 144-pin package, it is possible to remap some alternate functions to some other pins. This is achieved by software, by programming the AF remap and debug I/O configuration register (AFIO_MAPR). In this … mountain top orthodontics
