由于PA13和PA15与JTAG/SWD有口线复用，而且呢，PA13，PA15复位状态是这个！！所以在把其用作普通IO口时，需要禁用JTAG和SWD状态！​

 

#define __HAL_AFIO_REMAP_SWJ_ENABLE ( ) MODIFY_REG(AFIO->MAPR, AFIO_MAPR_SWJ_CFG, AFIO_MAPR_SWJ_CFG_RESET)

Enable the Serial wire JTAG configuration.

Note:

ENABLE: Full SWJ (JTAG-DP + SW-DP): Reset State

Return values:

None
