PA7–PA0
PA7–PA0 are general-purpose bidirectional I/O port pins. Use data
direction register A to configure port A pins as inputs or outputs.
PA7–PA0 also have mask selectable interrupt/pullup options.
PB7/SCK–
PB5/SDO
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.
PC7/V_RH–PC0
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.
PD7/TCAP and PD5
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.
TCMP
The TCMP pin is the output compare pin for the capture/compare timer.
