Port A
The Port A–H Data Direction sub-register is accessed through the Port A–H Control regis-
ter by writing 01H to the Port A–H Address register
DD[7:0]—Data Direction
These bits control the direction of the associated port pin. Port Alternate Function opera-
tion overrides the Data Direction register setting.
0 = Output. Data in the Port A–H Output Data register is driven onto the port pin.
1 = Input. The port pin is sampled and the value written into the Port A–H Input Data
