Power Management Controller
The Power Management Controller uses the Clock Generator outputs to provide:
the Processor Clock PCK
the Master Clock MCK
the USB Clock UDPCK
all the peripheral clocks, independently controllable
four programmable clock outputs
The Master Clock (MCK) is programmable from a few hundred Hz to the maximum operating fre-
quency of the device.
The Processor Clock (PCK) switches off when entering processor idle mode, thus allowing
reduced power consumption while waiting for an interrupt.

Advanced Interrupt Controller
Controls the interrupt lines (nIRQ and nFIQ) of an ARM Processor
Individually maskable and vectored interrupt sources
– Source 0 is reserved for the Fast Interrupt Input (FIQ)
– Source 1 is reserved for system peripherals (RTT, PIT, EFC, PMC, DBGU, etc.)
– Other sources control the peripheral interrupts or external interrupts
– Programmable edge-triggered or level-sensitive internal sources
– Programmable positive/negative edge-triggered or high/low level-sensitive external
sources
8-level Priority Controller
– Drives the normal interrupt nIRQ of the processor
– Handles priority of the interrupt sources
