RCC register map
The following table gives the RCC register map and the reset values.
RCC register map and reset values
Bit 1 LSIRDY: Internal low-speed oscillator ready
Bit 0 LSION: Internal low-speed oscillator enable
Set by hardware when a reset from the NRST pin occurs.
Cleared by writing to the RMVF bit.
0: No reset from NRST pin occurred
1: Reset from NRST pin occurred
Reserved, always read as 0.
Set by software to clear the reset flags.
0: No effect
1: Clear the reset flags
Reserved, always read as 0.
Set and cleared by hardware to indicate when the internal RC 40 kHz oscillator is stable.
After the LSION bit is cleared, LSIRDY goes low after 3 internal RC 40 kHz oscillator clock
cycles.
0: Internal RC 40 kHz oscillator not ready
1: Internal RC 40 kHz oscillator ready
Set and cleared by software.
0: Internal RC 40 kHz oscillator OFF
1: Internal RC 40 kHz oscillator ON
