Reserved. The reserved bit location is always read as 0. A value written to
this field has no effect.

OUTn
Controls the drive state of the corresponding GPn pin. These bits do not
affect the state of the pin when the pin is configured as an input. Reading
these bits returns the value of this register, not the state of the pin.
