Power status register 2
| REGLPS | Low-power regulator started This bit provides the information whether the low-power regulator is ready after a power-on reset or a Standby/Shutdown. If the Standby mode is entered while REGLPS bit is still cleared, the wakeup from Standby mode time may be increased. 0 (B_0x0): The low-power regulator is not ready 1 (B_0x1): The low-power regulator is ready |
| REGLPF | Low-power regulator flag This bit is set by hardware when the MCU is in Low-power run mode. When the MCU exits the Low-power run mode, this bit remains at 1 until the regulator is ready in main mode. A polling on this bit must be done before increasing the product frequency. This bit is cleared by hardware when the regulator is ready. 0 (B_0x0): The regulator is ready in main mode (MR) 1 (B_0x1): The regulator is in low-power mode (LPR) |
| VOSF | Voltage scaling flag A delay is required for the internal regulator to be ready after the voltage scaling has been changed. VOSF indicates that the regulator reached the voltage level defined with VOS bits of the PWR_CR1 register. 0 (B_0x0): The regulator is ready in the selected voltage range 1 (B_0x1): The regulator output voltage is changing to the required voltage level |
| PVDO | Programmable voltage detector output 0 (B_0x0): VDD is above the selected PVD threshold 1 (B_0x1): VDD is below the selected PVD threshold |
| PVMO1 | Peripheral voltage monitoring output: VDDA vs. 1.62 V Note: PVMO1 is cleared when PVM1 is disabled (PVME = 0). After enabling PVM1, the PVM1 output is valid after the PVM1 wakeup time. 0 (B_0x0): VDDA voltage is above PVM1 threshold (around 1.62 V). 1 (B_0x1): VDDA voltage is below PVM1 threshold (around 1.62 V). |
| PVMO2 | Peripheral voltage monitoring output: VDDA vs. 1.8 V Note: PVMO2 is cleared when PVM2 is disabled (PVME = 0). After enabling PVM2, the PVM2 output is valid after the PVM2 wakeup time. 0 (B_0x0): VDDA voltage is above PVM2 threshold (around 1.8 V). 1 (B_0x1): VDDA voltage is below PVM2 threshold (around 1.8 V). |
