PTA3–PTA0 are special-function, bidirectional I/O port pins. Any or all of
the port A pins can be programmed to serve as keyboard interrupt pins.

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.
When the port pins are configured for special-function mode (KBI),
pullups will be automatically engaged. As long as the port pins are in
special-function mode, the pullups will always be on.
PTB5–PTB0 are special-function, bidirectional I/O port pins that can also
be used for analog-to-digital converter (ADC) inputs. See
Ports (I/O)
There are no pullups associated with this port.
