8.4 Low-Power Mode Operation
Advance Information

The interrupt controller collects requests from multiple interrupt sources
and provides an interface to the CPU 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 CPU
is combinational. This allows the CPU to wake up during low-power stop
mode when all system clocks are stopped.
