Register overview: GPIO (base address port 0: 0x5000 0000; port 1: 0x5001 0000, port 2: 0x5002 0000;
port 3: 0x5003 0000)
8.3.1 GPIO data register
The GPIOnDATA register holds the current logic state of the pin (HIGH or LOW),
independently of whether the pin is configured as an GPIO input or output or as another
digital function. If the pin is configured as GPIO output, the current value of the
GPIOnDATA register is driven to the pin.
Table 79.
A read of the GPIOnDATA register always returns the current logic level (state) of the pin
independently of its configuration. Because there is a single data register for both the
value of the output driver and the state of the pin’s input, write operations have different
effects depending on the pin’s configuration:
The following rules apply when the pins are switched from input to output:

If a pin is configured as GPIO input, a write to the GPIOnDATA register has no effect
on the pin level. A read returns the current state of the pin.
If a pin is configured as GPIO output, the current value of GPIOnDATA register is
driven to the pin. This value can be a result of writing to the GPIOnDATA register, or it
can reflect the previous state of the pin if the pin is switched to GPIO output from
GPIO input or another digital function. A read returns the current state of the pin.
If a pin is configured as another digital function (input or output), a write to the
GPIOnDATA register has no effect on the pin level. A read returns the current state of
the pin even if it is configured as an output. This means that by reading the
GPIOnDATA register, the digital output or input value of a function other than GPIO on
that pin can be observed.
Pin is configured as input with a HIGH level applied:
– Change pin to output: pin drives HIGH level.
Pin is configured as input with a LOW level applied:
– Change pin to output: pin drives LOW level.
