+    
+    *** PVD configuration ***
+    =========================
+    [..]
+      (+) 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. This is done through
+          HAL_PWR_PVDConfig(), HAL_PWR_EnablePVD() functions.
+      (+) The PVD is stopped in Standby mode.
+      -@- PVD is not available on STM32F030x4/x6/x8
+
+    *** VDDIO2 Monitor Configuration ***
+    ====================================
+    [..]
+      (+) VDDIO2 monitor is used to monitor the VDDIO2 power supply by comparing it 
+          to VREFInt Voltage
+      (+) This monitor is internally connected to the EXTI line31
+          and can generate an interrupt if enabled. This is done through
+          HAL_PWR_EnableVddio2Monitor() function.
+      -@- VDDIO2 is available on STM32F07x/09x/04x
