RM0008 General-purpose and alternate-function I/Os (GPIOs and AFIOs)
Doc ID 13902 Rev 12 171/1096
To optimize the number of free GPIOs during debugging, this mapping can be configured in
different ways by programming the SWJ_CFG[1:0] bits in the AF remap and debug I/O
configuration register (AFIO_MAPR). Refer to Table 3 7
9.3.6 ADC alternate function remapping
