The IRQ/V
PA7–PA0 are general-purpose bidirectional I/O port pins. Use data
direction register A to configure port A pins as inputs or outputs.
Port B is a 3-pin bidirectional I/O port that shares its pins with the SIOP.
Use data direction register B to configure port B pins as inputs or
outputs.
Port C is an 8-pin bidirectional I/O port that shares five of its pins with the
ADC. Use data direction register C to configure port C pins as inputs or
outputs.
Port D is a 2-pin I/O port that shares one of its pins with the
capture/compare timer. Use data direction register D to configure port D
pins as inputs or outputs.
The TCMP pin is the output compare pin for the capture/compare timer.
