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.
The default register type for the GPIOCR register is RO for all GPIO pins, with the exception
of the NMI pin and the four JTAG/SWD pins (PB7 and PC[3:0]). These five pins are
currently the only GPIOs that are protected by the GPIOCR register. Because of this, the
register type for GPIO Port B7 and GPIO Port C[3:0] is R/W.
The default reset value for the GPIOCR register is 0x0000.00FF for all GPIO pins, with the
exception of the NMI pin and the four JTAG/SWD pins (PB7 and PC[3:0]). To ensure that
the JTAG port is not accidentally programmed as a GPIO, these four pins default to
non-committable. To ensure that the NMI pin is not accidentally programmed as the
non-maskable interrupt pin, it defaults to non-committable. Because of this, the default reset
value of GPIOCR for GPIO Port B is 0x0000.007F while the default reset value of GPIOCR
for Port C is 0x0000.00F0.
