Description
Software control of corresponding GPIO line (GPIO mode).
Hardware control of corresponding GPIO line (alternate

Note:
The default reset value for the GPIOAFSEL,
GPIOPUR, and GPIODEN registers are 0x0000.0000
for all GPIO pins, with the exception of the four
JTAG/SWD pins (PC[3:0]). These four pins default
to JTAG/SWD functionality. Because of this, the
default reset value of these registers for Port C is
0x0000.000F.
