Description
GPIO Alternate Function Select
0: Software control of corresponding GPIO line (GPIO mode).
1: Hardware control of corresponding GPIO line (alternate hardware
function).
Note:
The default reset value for the GPIOAFSEL, GPIOPUR, and
GPIODEN registers are 0x0000.0000 for all GPIO pins, with
the exception of the five JTAG/SWD pins (PB7 and PC[3:0]).
These five pins default to JTAG/SWD functionality. Because
of this, the default reset value of these registers for GPIO Port
B is 0x0000.0080 while the default reset value for Port C is
0x0000.000F.
