139/1128 DocID13902 Rev 15
Bit 11 HSERDYIE: HSE ready interrupt enable
Set and cleared by software to enable/disable interrupt caused by the external 3-25 MHz
oscillator stabilization.
0: HSE ready interrupt disabled
1: HSE ready interrupt enabled
Bit 10 HSIRDYIE: HSI ready interrupt enable
Set and cleared by software to enable/disable interrupt caused by the internal 8 MHz RC
oscillator stabilization.
0: HSI ready interrupt disabled
1: HSI ready interrupt enabled
Bit 9 LSERDYIE: LSE ready interrupt enable
Set and cleared by software to enable/disable interrupt caused by the external 32 kHz
oscillator stabilization.
0: LSE ready interrupt disabled
1: LSE ready interrupt enabled
Bit 8 LSIRDYIE: LSI ready interrupt enable
Set and cleared by software to enable/disable interrupt caused by internal RC 40 kHz
oscillator stabilization.
0: LSI ready interrupt disabled
1: LSI ready interrupt enabled
Bit 7 CSSF: Clock security system interrupt flag
Set by hardware when a failure is detected in the external 3-25 MHz oscillator. It is cleared
by software setting the CSSC bit.
0: No clock security interrupt caused by HSE clock failure
1: Clock security interrupt caused by HSE clock failure
Bit 6 PLL3RDYF: PLL3 Ready Interrupt flag
Set by hardware when the PLL3 locks and PLL3RDYIE is set. It is cleared by software
setting the PLL3RDYC bit.
0: No clock ready interrupt caused by PLL3 lock
1: Clock ready interrupt caused by PLL3 lock
Bit 5 PLL2RDYF: PLL2 Ready Interrupt flag
Set by hardware when the PLL2 locks and PLL2RDYDIE is set. It is cleared by software
setting the PLL2RDYC bit.
0: No clock ready interrupt caused by PLL2 lock
1: Clock ready interrupt caused by PLL2 lock
Bit 4 PLLRDYF: PLL ready interrupt flag
Set by hardware when the PLL locks and PLLRDYDIE is set. It is cleared by software
setting the PLLRDYC bit.
0: No clock ready interrupt caused by PLL lock
1: Clock ready interrupt caused by PLL lock
Bit3 HSERDYF: HSE ready interrupt flag
Set by hardware when External High Speed clock becomes stable and HSERDYIE is set. It
is cleared by software setting the HSERDYC bit.
0: No clock ready interrupt caused by the external 3-25 MHz oscillator
1: Clock ready interrupt caused by the external 3-25 MHz oscillator
