| WP1 | Wakeup pin WKUP1 polarity This bit defines the polarity used for an event detection on external wake-up pin, WKUP1 0 (B_0x0): Detection on high level (rising edge) 1 (B_0x1): Detection on low level (falling edge) |
| WP2 | Wakeup pin WKUP2 polarity This bit defines the polarity used for an event detection on external wake-up pin, WKUP2 0 (B_0x0): Detection on high level (rising edge) 1 (B_0x1): Detection on low level (falling edge) |
| WP3 | Wakeup pin WKUP3 polarity This bit defines the polarity used for an event detection on external wake-up pin, WKUP3 0 (B_0x0): Detection on high level (rising edge) 1 (B_0x1): Detection on low level (falling edge) |
| WP4 | Wakeup pin WKUP4 polarity This bit defines the polarity used for an event detection on external wake-up pin, WKUP4 0 (B_0x0): Detection on high level (rising edge) 1 (B_0x1): Detection on low level (falling edge) |
| WP5 | Wakeup pin WKUP5 polarity This bit defines the polarity used for an event detection on external wake-up pin, WKUP5 0 (B_0x0): Detection on high level (rising edge) 1 (B_0x1): Detection on low level (falling edge) |
| VBE | VBAT battery charging enable 0 (B_0x0): VBAT battery charging disable 1 (B_0x1): VBAT battery charging enable |
| VBRS | VBAT battery charging resistor selection 0 (B_0x0): Charge VBAT through a 5 kOhms resistor 1 (B_0x1): Charge VBAT through a 1.5 kOhms resistor |
