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_CSR1).
 - The PVD can use an external input analog voltage (PVD_IN) which is compared 
   internally to VREFINT. The PVD_IN (PE6) has to be configured in Analog mode 
   when PWR_PVDLevel_PVDIn is selected (PLS[2:0] = 111).
 - A PVDO flag is available to indicate if VDD/VDDA is higher or lower than the 
   PVD threshold. An interrupt is generated in case enabled for PVD. 
 - The PVD interrup event has the capability to wake up the CPU from Halt/Active Halt modes.
