由于PA13和PA15與JTAG/SWD有口線復用，而且呢，PA13，PA15復位狀態是這個！！所以在把其用作普通IO口時，需要禁用JTAG和SWD狀態！​

 

#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
