The peripherals clock had different clock source switch setting which depends on the different
peripheral. Please refer the CLKSEL1 and CLKSEL2 register description in 5.3.7.
When chip enters into power down mode, system clocks, some clock sources, and some
peripheral clocks will be disabled. Some clock sources and peripherals clock are still active in
power down mode.
For theses clocks which still keep active list below:
Peripherals Clock
Power down mode (Deep Sleep Mode) Clock

Clock Generator
Peripherals Clock (When these IP adopt 32.768 kHz or 10 kHz as clock source)
Internal 10 kHz oscillator clock
External 32.768 kHz crystal clock
