Functions

void PWR_PVDLevelConfig (uint32_t PWR_PVDLevel)
 Configures the voltage threshold detected by the Power Voltage Detector(PVD).
void PWR_PVDCmd (FunctionalState NewState)
 Enables or disables the Power Voltage Detector(PVD).

Detailed Description

PVD configuration functions. 

 ===============================================================================
                    ##### PVD configuration functions #####
  ==============================================================================
  [..]
  (+) 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.
