  [..]
  (+) The PVD is used to monitor the VDD power supply by comparing it to a threshold
      selected by the PVD Level (PLS[2:0] bits in the PWR_CR).
  (+) A PVDO flag is available to indicate if VDD/VDDA is higher or lower than the 
      PVD threshold. This event is internally connected to the EXTI line16
      and can generate an interrupt if enabled through the EXTI registers.
  (+) The PVD is stopped in Standby mode.

Function Documentation

void PWR_PVDCmd ( FunctionalState  NewState)

Enables or disables the Power Voltage Detector(PVD).

Parameters
NewState,:new state of the PVD. This parameter can be: ENABLE or DISABLE.
Return values
None
void PWR_PVDLevelConfig ( uint32_t  PWR_PVDLevel)

  • PWR_PVDLevel_7
Note
Refer to the electrical characteristics of your device datasheet for more details about the voltage threshold corresponding to each detection level.
Return values
None
