Power Management Controller
Figure 9-2.
The Power Management Controller uses the clock generator outputs to provide:
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.
The LCD Controller clock is SCLK.
• The Processor Clock PCK
• The Master Clock MCK
• All the peripheral clocks, independently controllable
• Three programmable clock outputs PCKx
