Chapter 2 Port Integration Module (S12XEPIMV1)
Most I/O pins can be configured by register bits to select data direction and drive strength, to enable and
select pull-up or pull-down devices.
2.1.2
The Port Integration Module includes these distinctive registers:
A standard port pin has the following minimum features:
Optional features supported on dedicated pins:
