PWR wakeup status register
| WUF1 | Wakeup 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 when WUSEL ≠ 11, or by hardware when WUPEN1 = 0. |
| WUF2 | Wakeup 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 when WUSEL ≠ 11, or by hardware when WUPEN2 = 0. |
| WUF3 | Wakeup 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 when WUSEL ≠ 11, or by hardware when WUPEN3 = 0. |
| WUF4 | Wakeup 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 when WUSEL ≠ 11, or by hardware when WUPEN4 = 0. |
| WUF5 | Wakeup 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 when WUSEL ≠ 11, or by hardware when WUPEN5 = 0. |
| WUF6 | Wakeup 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 WUSEL ≠ 11, or by hardware when WUPEN6 = 0. If WUSEL = 11, this bit is cleared by hardware when all internal wakeup source are cleared. |
| WUF7 | Wakeup 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 WUSEL ≠ 11, or by hardware when WUPEN7 = 0. If WUSEL = 11, this bit is cleared by hardware when all internal wakeup source are cleared. |
| WUF8 | Wakeup 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 WUSEL ≠ 11, or by hardware when WUPEN8 = 0. If WUSEL = 11, this bit is cleared by hardware when all internal wakeup source are cleared. |
