If 01H in Port A–C Address Register, accessible through the Port A–C Control Register
The Port A–C Control Registers set the GPIO port operation. The value in the correspond-
ing Port A–C Address Register determines the control sub-registers accessible using the
Port A–C Control Register
PCTL[7:0]—Port Control
The Port Control Register provides access to all sub-registers that configure the GPIO Port
operation.
Port A–C Data Direction Sub-Registers
The Port A–C Data Direction sub-register is accessed through the Port A–C Control
register by writing 01H to the Port A–C 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–C Output Data Register is driven onto the port pin.
1 = Input. The port pin is sampled and the value written into the Port A–C Input
Port A–C Alternate Function Sub-Registers
The Port A–C Alternate Function sub-register
Port A–C Control Register by writing
Port A–C Alternate Function sub-registers select the alternate functions for the selected
Data Register. The output driver is tri-stated.
