PTA7–PTA0 are general-purpose, bidirectional I/O port pins. Any or all
of the port A pins can be programmed to serve as keyboard interrupt
pins.
Keyboard Interrupt Module
These port pins also have selectable pullups when configured for input
mode. The pullups are disengaged when configured for output mode.
The pullups are selectable on an individual port bit basis.
PTB7–PTB0 are general-purpose, bidirectional I/O port pins that can
also be used for analog-to-digital converter (ADC) inputs.
