Reset and clock control (RCC)
Bit 2 HSI16RDYF: HSI16 ready interrupt flag
This bit is reset by software by writing the HSI16RDYC bit. It is set by hardware when the
HSE clock becomes stable and the HSI16RDYIE is set.
0: No clock ready interrupt caused by HSI16 clock failure
1: Clock ready interrupt caused by HSI16 clock failure
Bit 1 LSERDYF: LSE ready interrupt flag
This bit is reset by software by writing the LSERDYC bit. It is set by hardware when the LSE
clock becomes stable and the LSERDYIE is set.
0: No clock ready interrupt caused by LSE clock failure
1: Clock ready interrupt caused by LSE clock failure
Bit 0 LSIRDYF: LSI ready interrupt flag
This bit is reset by software by writing the LSIRDYC bit. It is set by hardware when the LSI
clock becomes stable and the LSIRDYIE is set.
0: No clock ready interrupt caused by LSI clock failure
1: Clock ready interrupt caused by LSI clock failure
7.3.7
Clock interrupt clear register (RCC_CICR)
Address: 0x18
Reset value: 0x0000 0000
Access: no wait state, word, half-word and byte access
