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
three 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.
