Description

RCC clock interrupt flag register

Fields

LSIRDYF

LSI ready interrupt flag This bit is set by hardware when the LSI clock becomes stable and LSIRDYIE is set. It is cleared by software by�setting the LSIRDYC bit.

0 (B_0x0): No clock ready interrupt caused by the LSI oscillator

1 (B_0x1): Clock ready interrupt caused by the LSI oscillator

LSERDYF

LSE ready interrupt flag This bit is set by hardware when the LSE clock becomes stable and LSERDYIE is set. It is cleared by software by setting the LSERDYC bit.

0 (B_0x0): No clock ready interrupt caused by the LSE oscillator

1 (B_0x1): Clock ready interrupt caused by the LSE oscillator

MSISRDYF

MSIS ready interrupt flag This bit is set by hardware when the MSIS clock becomes stable and MSISRDYIE is set. It�is cleared by software by setting the MSISRDYC bit.

0 (B_0x0): No clock ready interrupt caused by the MSIS oscillator

1 (B_0x1): Clock ready interrupt caused by the MSIS oscillator

HSIRDYF

HSI16 ready interrupt flag This bit is set by hardware when the HSI16 clock becomes stable and HSIRDYIE = 1 in�response to setting the HSION (see RCC_CR). When HSION = 0 but the HSI16 oscillator is enabled by the peripheral through a clock request, this bit is not set and no interrupt is generated. This bit is cleared by software by setting the HSIRDYC bit.

0 (B_0x0): No clock ready interrupt caused by the HSI16 oscillator

1 (B_0x1): Clock ready interrupt caused by the HSI16 oscillator

HSERDYF

HSE ready interrupt flag This bit is set by hardware when the HSE clock becomes stable and HSERDYIE is set. It is cleared by software by setting the HSERDYC bit.

0 (B_0x0): No clock ready interrupt caused by the HSE oscillator

1 (B_0x1): Clock ready interrupt caused by the HSE oscillator

HSI48RDYF

HSI48 ready interrupt flag This bit is set by hardware when the HSI48 clock becomes stable and HSI48RDYIE is set. it�is cleared by software by setting the HSI48RDYC bit.

0 (B_0x0): No clock ready interrupt caused by the HSI48 oscillator

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

PLL1RDYF

PLL1 ready interrupt flag This bit is set by hardware when the PLL1 locks and PLL1RDYIE is set. It is cleared by software by setting the PLL1RDYC bit.

0 (B_0x0): No clock ready interrupt caused by PLL1 lock

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

PLL2RDYF

PLL2 ready interrupt flag This bit is set by hardware when the PLL2 locks and PLL2RDYIE is set. It is cleared by software by setting the PLL2RDYC bit.

0 (B_0x0): No clock ready interrupt caused by PLL2 lock

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

PLL3RDYF

PLL3 ready interrupt flag This bit is set by hardware when the PLL3 locks and PLL3RDYIE is set. It is cleared by software by setting the PLL3RDYC bit.

0 (B_0x0): No clock ready interrupt caused by PLL3 lock

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

CSSF

Clock security system interrupt flag This bit is set by hardware when a failure is detected in the HSE oscillator. It is cleared by software by setting the CSSC bit.

0 (B_0x0): No clock security interrupt caused by HSE clock failure

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

MSIKRDYF

MSIK ready interrupt flag This bit is set by hardware when the MSIK clock becomes stable and MSIKRDYIE is set. It is cleared by software by setting the MSIKRDYC bit.

0 (B_0x0): No clock ready interrupt caused by the MSIK oscillator

1 (B_0x1): Clock ready interrupt caused by the MSIK oscillator

SHSIRDYF

SHSI ready interrupt flag This bit is set by hardware when the SHSI clock becomes stable and SHSIRDYIE is set. It is cleared by software by setting the SHSIRDYC bit.

0 (B_0x0): No clock ready interrupt caused by the SHSI oscillator

1 (B_0x1): Clock ready interrupt caused by the SHSI oscillator
