5.3.1
The clock controller generates the clocks for the whole chip, including system clocks and all
peripheral clocks. The clock controller also implements the power control function with the
individually clock ON/OFF control, clock source selection and a clock divider. The chip will not
enter power down mode until CPU sets the power down enable bit (PWR_DOWN_EN) and
Cortex-M0 core executes the WFI instruction. After that, chip enter power down mode and wait for
wake-up interrupt source triggered to leave power down mode. In the power down mode, the
clock controller turns off the external 4~24 MHz high speed crystal and internal 22.1184 MHz high
speed oscillator to reduce the overall system power consumption.
