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.
7.1
The SIM provides a centralized interrupt controller for all MCF5272 interrupt sources, which consist of
the following:

Four interrupt control registers (ICR1–ICR4), which are used to assign interrupt levels to the
interrupt sources.
The interrupt source register (ISR) allows reading the instantaneous value of each interrupt source.
The programmable interrupt transition register (PITR) specifies the triggering transition of the
external interrupt inputs.
The programmable interrupt wakeup register (PIWR) specifies which interrupt sources can
reactivate the CPU from low-power sleep or stop mode.
The programmable interrupt vector register (PIVR) specifies which vector number is returned in
response to an interrupt acknowledge cycle.
