Description

RCC clock source interrupt flag register

Fields

LSIRDYF

LSI ready interrupt flag Reset by software by writing LSIRDYC bit. Set by hardware when the LSI clock becomes stable and LSIRDYIE is set.

0 (B_0x0): no clock ready interrupt caused by the LSI (default after reset)

1 (B_0x1): clock ready interrupt caused by the LSI

LSERDYF

LSE ready interrupt flag Reset by software by writing LSERDYC bit. Set by hardware when the LSE clock becomes stable and LSERDYIE is set.

0 (B_0x0): no clock ready interrupt caused by the LSE (default after reset)

1 (B_0x1): clock ready interrupt caused by the LSE

HSIRDYF

HSI ready interrupt flag Reset by software by writing HSIRDYC bit. Set by hardware when the HSI clock becomes stable and HSIRDYIE is set.

0 (B_0x0): no clock ready interrupt caused by the HSI (default after reset)

1 (B_0x1): clock ready interrupt caused by the HSI

HSERDYF

HSE ready interrupt flag Reset by software by writing HSERDYC bit. Set by hardware when the HSE clock becomes stable and HSERDYIE is set.

0 (B_0x0): no clock ready interrupt caused by the HSE (default after reset)

1 (B_0x1): clock ready interrupt caused by the HSE

CSIRDYF

CSI ready interrupt flag Reset by software by writing CSIRDYC bit. Set by hardware when the CSI clock becomes stable and CSIRDYIE is set.

0 (B_0x0): no clock ready interrupt caused by the CSI (default after reset)

1 (B_0x1): clock ready interrupt caused by the CSI

HSI48RDYF

HSI48 ready interrupt flag Reset by software by writing HSI48RDYC bit. Set by hardware when the HSI48 clock becomes stable and HSI48RDYIE is set.

0 (B_0x0): no clock ready interrupt caused by the HSI48 oscillator (default after reset)

1 (B_0x1): clock ready interrupt caused by the HSI48 oscillator

PLL1RDYF

PLL1 ready interrupt flag Reset by software by writing PLL1RDYC bit. Set by hardware when the PLL1 locks and PLL1RDYIE is set.

0 (B_0x0): no clock ready interrupt caused by PLL1 lock (default after reset)

1 (B_0x1): clock ready interrupt caused by PLL1 lock

PLL2RDYF

PLL2 ready interrupt flag Reset by software by writing PLL2RDYC bit. Set by hardware when the PLL2 locks and PLL2RDYIE is set.

0 (B_0x0): no clock ready interrupt caused by PLL2 lock (default after reset)

1 (B_0x1): clock ready interrupt caused by PLL2 lock

PLL3RDYF

PLL3 ready interrupt flag Reset by software by writing PLL3RDYC bit. Set by hardware when the PLL3 locks and PLL3RDYIE is set.

0 (B_0x0): no clock ready interrupt caused by PLL3 lock (default after reset)

1 (B_0x1): clock ready interrupt caused by PLL3 lock

LSECSSF

LSE clock security system interrupt flag Reset by software by writing LSECSSC bit. Set by hardware when a failure is detected on the external 32 kHz oscillator and LSECSSIE is set.

0 (B_0x0): no failure detected on the external 32 kHz oscillator (default after reset)

1 (B_0x1): failure detected on the external 32 kHz oscillator

HSECSSF

HSE clock security system interrupt flag Reset by software by writing HSECSSC bit. Set by hardware in case of HSE clock failure.

0 (B_0x0): no clock security interrupt caused by HSE clock failure (default after reset)

1 (B_0x1): clock security interrupt caused by HSE clock failure
