Doc ID 13902 Rev 12 103/1096
7.3.4 APB2 peripheral reset register (RCC_APB2RSTR)
Address offset: 0x0C
Reset value: 0x00000 0000
Access: no wait state, word, half-word and byte access
Bit 1 LSERDYF: LSE ready interrupt flag
Set by hardware when the External Low Speed clock becomes stable and LSERDYDIE is
set.
Cleared by software setting the LSERDYC bit.
0: No clock ready interrupt caused by the external 32 kHz oscillator
1: Clock ready interrupt caused by the external 32 kHz oscillator
Bit 0 LSIRDYF: LSI ready interrupt flag
Set by hardware when the internal low speed clock becomes stable and LSIRDYDIE is set.
Cleared by software setting the LSIRDYC bit.
0: No clock ready interrupt caused by the internal RC 40 kHz oscillator
1: Clock ready interrupt caused by the internal RC 40 kHz oscillator
