Clocks
The STM32W108 integrates four oscillators:
●
●
●
●
Bit 4 SW_RST: When set to ‘1’, the reset is due to a software reset.
Bit 3 W_DOG: When set to ‘1’, the reset is due to watchdog expiration.
Bit 2 RSTB_PIN: When set to ‘1’, the reset is due to an external reset pin signal.
Bit 1 POWER_LV: When set to ‘1’, the reset is due to the application of a Core power supply (or
Bit 0 POWER_HV: Always set to ‘1’, Normal power applied
High frequency RC oscillator
24 MHz crystal oscillator
10 kHz RC oscillator
32.768 kHz crystal oscillator
previously failed).
