a. The default reset value for the GPIOAFSEL register is 0x00000000 for all GPIO pins, with the exception of the five JTAG pins
(PB7 and PC[3:0]. These five pins default to JTAG functionality. Because of this, the default reset value of GPIOAFSEL for
GPIO Port B is 0x00000080 while the default reset value of GPIOAFSEL for Port C is 0x0000000F.
