Port Integration Module (S12XEPIMV1)
2.1
2.1.1
The S12XE Family Port Integration Module establishes the interface between the peripheral modules
including the non-multiplexed External Bus Interface module (S12X_EBI) 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.
