GPxDAT are Port x configuration and data registers. They
configure the direction of the GPIO pins of Port x, set the
output value for the pins configured as output, and store the
input value of the pins configured as input.

Bit
Description
31 to 24
Direction of the data.
This bit is set to 1 by the user to configure the GPIO
pin as an output.
This bit is cleared to 0 by the user to configure the
GPIO pin as an input.
23 to 16
Port x data output.
15 to 8
Reflect the state of port x pins at reset (read only).
7 to 0
Port x data input (read only).
