Description
Reserved for factory use
For write operations the GPIO pin operates as an output. Writing
a 1 to the GPIOn bit sets the GPIOn pin to high impedance.
Writing a 0 sets the GPIOn pin to logic low. An external pullup
resistor is required when using the GPIO as an output.
For read operations the GPIO pin operates as an input. Read
the GPIOn bit to receive the status of the GPIOn pin.
After power-on reset, or any forced hardware or software reset,
the GPIOn pin is in a high-impedance state.
