Port Integration Module (S12XSPIMV1)
Revision History
2.1
2.1.1
The S12XS family Port Integration Module establishes the interface between the peripheral modules and
the I/O pins for all ports. It controls the electrical pin properties as well as the signal prioritization and
multiplexing on shared pins.
This document covers:
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.
