Note:
The default reset value for the GPIOAFSEL register is 0x0000.0000 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
0x0000.0080 while the default reset value for Port C is 0x0000.000F.
