35.1 Description

The Power Management Controller (PMC) optimizes power consumption by controlling all system and user peripheral clocks. The PMC enables/disables the clock inputs to many of the peripherals and to the processor.

The Slow Clock Controller (SCKC) selects the source of TD_SLCK (drives the real-time part (RTT/RTC)). The source of MD_SLCK (drives the rest of the system controller: wake-up logic, watchdog, PMC, etc.) is always the slow RC oscillator.

For the out of ROM configuration, refer to the section “Boot Strategies”.
