PWR control status register 1
| BREN | Backup regulator enable When set, the backup regulator (used to maintain the backup RAM content in Standby and VBAT modes) is enabled. If BREN is reset, the backup regulator is switched off. The backup RAM can still be used in Run and Stop modes. However, its content will be lost in Standby and VBAT modes. If BREN is set, the application must wait till the backup regulator ready flag (BRRDY) is set to indicate that the data written into the SRAM will be maintained in Standby and VBAT modes. 0 (B_0x0): Backup regulator disabled. 1 (B_0x1): Backup regulator enabled. |
| MONEN | VBAT and temperature monitoring enable When set, the VBAT supply and temperature monitoring is enabled. Note: VBAT and temperature monitoring are only available when the backup regulator is enabled (BREN bit set to 1). 0 (B_0x0): VBAT and temperature monitoring disabled. 1 (B_0x1): VBAT and temperature monitoring enabled. |
| BRRDY | Backup regulator ready This bit is set by hardware to indicate that the backup regulator is ready. 0 (B_0x0): Backup regulator not ready. 1 (B_0x1): Backup regulator ready. |
| VBATL | VBAT level monitoring versus low threshold 0 (B_0x0): VBAT level above low threshold level. 1 (B_0x1): VBAT level equal or below low threshold level. |
| VBATH | VBAT level monitoring versus high threshold 0 (B_0x0): VBAT level below high threshold level. 1 (B_0x1): VBAT level equal or above high threshold level. |
| TEMPL | Temperature level monitoring versus low threshold 0 (B_0x0): Temperature above low threshold level. 1 (B_0x1): Temperature equal or below low threshold level. |
| TEMPH | Temperature level monitoring versus high threshold 0 (B_0x0): Temperature below high threshold level. 1 (B_0x1): Temperature equal or above high threshold level. |
