PCTL[7:0]—Port Control
The port control register provides access to all subregisters that configure the GPIO port
operation.
The Port A–D data direction subregister is accessed through the Port A–D control register
by writing 01H to the Port A–D address register. See
DD[7:0]—Data direction
These bits control the direction of the associated port pin. Port Alternate Function
operation overrides the Data direction register setting.
0 = Output. Data in the Port A–D output data register is driven onto the port pin.
1 = Input. The port pin is sampled and the value written into the Port A–D input data
register. The output driver is tristated.
The Port A–D Alternate function subregister is accessed through the Port A–D control
register by writing
Port A–D Alternate function subregisters enable the Alternate function selection on pins.
If disabled, the pins functions as GPIO. If enabled, select one of four Alternate functions
using Alternate function set subregisters 1 and 2 as described in the
Function Set 1 Subregisters
