6.9 General purpose parallel I/O
Device pins that are not connected to a specific peripheral function are controlled by
the GPIO registers. Pins may be dynamically configured as inputs or outputs.
Separate registers allow setting or clearing any number of outputs simultaneously.
The value of the output register may be read back, as well as the current state of the
port pins.
6.9.1
Features
Direction control of individual bits.
Separate control of output set and clear.
All I/O default to inputs after reset.
