PWR wakeup status register
| WUF1 | Wakeup and interrupt pending flag 1 This bit is set when a wakeup event is detected on WKUP1 pin. This bit is cleared by writing 1 in the CWUF1 bit of PWR_WUSCR or by hardware when WUPEN1 = 0. |
| WUF2 | Wakeup and interrupt pending flag 2 This bit is set when a wakeup event is detected on WKUP2 pin. This bit is cleared by writing 1 in the CWUF2 bit of PWR_WUSCR or by hardware when WUPEN2 = 0. |
| WUF3 | Wakeup and interrupt pending flag 3 This bit is set when a wakeup event is detected on WKUP3 pin. This bit is cleared by writing 1 in the CWUF3 bit of PWR_WUSCR or by hardware when WUPEN3 = 0. |
| WUF4 | Wakeup and interrupt pending flag 4 This bit is set when a wakeup event is detected on WKUP4 pin. This bit is cleared by writing 1 in the CWUF4 bit of PWR_WUSCR or by hardware when WUPEN4 = 0. |
| WUF5 | Wakeup and interrupt pending flag 5 This bit is set when a wakeup event is detected on WKUP5 pin. This bit is cleared by writing 1 in the CWUF5 bit of PWR_WUSCR or by hardware when WUPEN5 = 0. |
| WUF6 | Wakeup and interrupt pending flag 6 This bit is set when a wakeup event is detected on WKUP6 pin. This bit is cleared by writing 1 in the CWUF6 bit of PWR_WUSCR when WUSEL6 different 11, or by hardware when WUPEN6 = 0. When WUSEL6 = 11, this bit is cleared by hardware when all associated internal wakeup source are cleared. When WUSEL6 = 11, no WKUP interrupt is generated |
| WUF7 | Wakeup and interrupt pending flag 7 This bit is set when a wakeup event is detected on WKUP7 pin. This bit is cleared by writing 1 in the CWUF7 bit of PWR_WUSCR when WUSEL7 different 11, or by hardware when WUPEN7 = 0. When WUSEL7 = 11, this bit is cleared by hardware when all associated internal wakeup source are cleared. When WUSEL7 = 11, no WKUP interrupt is generated. |
| WUF8 | Wakeup and interrupt pending flag 8 This bit is set when a wakeup event is detected on WKUP8 pin. This bit is cleared by writing 1 in the CWUF8 bit of PWR_WUSCR when WUSEL8 different 11, or by hardware when WUPEN8 = 0. When WUSEL8 = 11, this bit is cleared by hardware when all associated internal wakeup source are cleared. When WUSEL8 = 11, no WKUP interrupt is generated |
