|
(+) 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.</pre> <h2 class="groupheader">Function Documentation</h2>
