Port Output
Many of the GPIO port pins can be used as both general-purpose I/O and to provide access
to on-chip peripheral functions such as the timers and serial communication devices. The
Port A–H Alternate Function sub-registers configure these pins for either general-purpose
I/O or alternate function operation. When a pin is configured for alternate function, control
of the port pin direction (input/output) is passed from the Port A–H Data Direction regis-
ters to the alternate function assigned to this pin.
