When chip enter into power down mode, most of clock sources, peripheral clocks and system
clock will be disabled. Some of clock sources and peripherals clock are still active in power down
mode.
For theses clocks which still keep active list below:
Clock Generator
Peripherals Clock (When these IP adopt 10 kHz as clock source)
Power Down Mode (Deep Sleep Mode) Clock
Internal 10 kHz oscillator clock
Watch Dog Clock
Timer 0/1/2/3 Clock
PWM Clock
