Bit 6 PVDOF: PVD output flag
This bit is set and cleared by hardware.
0: VDD/VDDA is above the VPVD threshold
1: VDD/VDDA is below the VPVD threshold
这个是控制配置,但是怎么做了?
有人说需要低压标志,固件库里:
enum PWR_FLAG_TypeDef { PWR_FLAG_PVDOF = (uint8_t)0x40, PWR_FLAG_PVDIF = (uint8_t)0x20, PWR_FLAG_VREFINTF = (uint8_t)0x01 }
PVDOF这个就是低压高压的。又该怎么做?
