Programmable voltage detector (PVD)

The PVD can be used to monitor the V
selected through PVDRT[2:0] bits (rising thresholds) and PVDFT[2:0] bits (falling
thresholds) in the
lower voltage level than
The PVD is enabled by setting the PVDE bit.
A PVDO flag is available in the
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 output
interrupt can be generated when V
rises above the PVD threshold depending on EXTI line16 rising/falling edge configuration.
As an example, the service routine could perform emergency shutdown tasks.
