Chapter 9
Interrupt Controller
This chapter describes the operation of the interrupt controller portion of the system
integration module (SIM). It includes descriptions of the registers in the interrupt controller
memory map and the interrupt priority scheme.
9.1 Overview
The SIM provides a centralized interrupt controller for all MCF5407 interrupt sources,
which consist of the following:
