Power supply thresholds
1.
The PVD is available on all STM32L devices and it is enabled or disabled by software.
2.
The BOR is available only on devices operating from 1.8 to 3.6 V, and unless disabled by option byte it will mask the
POR/PDR threshold.
3.
When the BOR is disabled by option byte, the reset is asserted when VDD goes below PDR level
4.
For devices operating from 1.65 to 3.6 V, there is no BOR and the reset is released when VDD goes above POR level and
asserted when VDD goes below PDR level
