• Manufacturer Part Number: mm912f634
• Description: Mm912f634 - Integrated S12 Based Relay Driver With Lin
• Manufacturer: Freescale Semiconductor, Inc

Functional Description and Application Information
4.27
4.27.1
The Port Integration Module (PIM) establishes the interface between the S12I32 peripheral modules SPI and the Die-To-Die
Interface module (D2DI) to the I/O pins of the MCU. Depending on the package option the D2DI related pins may or may not be
available externally; if used in a dual-die package this interface is internal.
All pins support general purpose I/O functionality if not in use by the peripheral module. The PIM controls the signal prioritization
and multiplexing on the shared pins and the pull-down functionality on specific pins.
4.27.2
The Port Integration Module includes these distinctive registers:
A standard port A pin has the following features:
A standard port C and D pin has the following features:
