Interrupt Controller (INTC)

10.1 Introduction

This chapter describes the interrupt controller (INTC), which schedules interrupt requests (IRQs) from

software and internal peripherals to the e200z6 core. The INTC provides interrupt prioritization and

preemption, interrupt masking, interrupt priority elevation, and protocol support.

Interrupts implemented by the MPC5553 and the MPC5554 are defined in the e200z6 PowerPC

Core
