Interrupt Controller Module
7.2 Introduction
7.3 Features
7.4 Low-Power Mode Operation
Technical Data
154
The interrupt controller collects requests from multiple interrupt sources
and provides an interface to the processor core interrupt logic.
Features of the interrupt controller module include:
The interrupt controller is not affected by any low-power modes. All logic
between the input sources and generating the raw interrupt to the
M•CORE processor is combinational. This allows the M•CORE
processor to wake up during low-power stop mode when all system
clocks are stopped.
