PCTL[7:0]—Port Control
The Port Control register provides access to all sub-registers that configure the GPIO Port
operation.
The Port A–D Data Direction sub-register is accessed through the Port A–D Control
register by writing 01H to the Port A–D Address register
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 Reg-
ister. The output driver is tristated.
The Port A–D Alternate Function sub-register
Port A–D Control register by writing
Alternate Function sub-registers enable the alternate function selection on pins. If dis-
abled, pins functions as GPIO. If enabled, select one of four alternate functions using
alternate function set subregisters 1 and 2 as described in the
