Port Integration Module (S12XEP100PIMV1)
2.1
Introduction
2.1.1
Overview
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.
This document covers:
•
Port A and B used as address output of the S12X_EBI
•
Port C and D used as data I/O of the S12X_EBI
•
Port E associated with the S12X_EBI control signals and the IRQ, XIRQ interrupt inputs
•
Port K associated with address output and control signals of the S12X_EBI
•
Port T associated with 1 ECT module
•
Port S associated with 2 SCI and 1 SPI modules
•
Port M associated with 4 MSCAN and 1 SCI module
•
Port P connected to the PWM and 2 SPI modules - inputs can be used as an external interrupt source
•
Port H associated with 4 SCI modules - inputs can be used as an external interrupt source
•
Port J associated with 1 MSCAN, 1 SCI, 2 IIC modules and chip select outputs - inputs can be used
as an external interrupt source
•
Port AD0 and AD1 associated with two 16-channel ATD modules
•
Port R associated with 1 stardard timer (TIM) module
•
Port L associated with 4 SCI modules
•
Port F associated with IIC, SCI and chip select outputs
