PWR wakeup enable and polarity register
| WKUPEN1 | Enable Wakeup Pin WKUPn, (n = 4, 3, 2, 1) Each bit is set and cleared by software. Note: An additional wakeup event is detected if WKUPn+1 pin is enabled (by setting the WKUPENn bit) when WKUPn pin level is already high when WKUPPn+1 selects rising edge, or low when WKUPPn selects falling edge. 0 (B_0x0): An event on WKUPn pin does not wakeup the system from Standby mode. 1 (B_0x1): A rising or falling edge on WKUPn pin wakes-up the system from Standby mode. |
| WKUPEN2 | Enable Wakeup Pin WKUPn, (n = 4, 3, 2, 1) Each bit is set and cleared by software. Note: An additional wakeup event is detected if WKUPn+1 pin is enabled (by setting the WKUPENn bit) when WKUPn pin level is already high when WKUPPn+1 selects rising edge, or low when WKUPPn selects falling edge. 0 (B_0x0): An event on WKUPn pin does not wakeup the system from Standby mode. 1 (B_0x1): A rising or falling edge on WKUPn pin wakes-up the system from Standby mode. |
| WKUPEN3 | Enable Wakeup Pin WKUPn, (n = 4, 3, 2, 1) Each bit is set and cleared by software. Note: An additional wakeup event is detected if WKUPn+1 pin is enabled (by setting the WKUPENn bit) when WKUPn pin level is already high when WKUPPn+1 selects rising edge, or low when WKUPPn selects falling edge. 0 (B_0x0): An event on WKUPn pin does not wakeup the system from Standby mode. 1 (B_0x1): A rising or falling edge on WKUPn pin wakes-up the system from Standby mode. |
