The device features an embedded programmable voltage detector (PVD) that monitors the

the MCU into a safe state. The PVD is enabled by software.
Voltage regulator
The regulator has three operation modes: main (MR), low power (LPR), and power-down.

The device has an integrated power-on reset (POR)/power-down reset (PDR) circuitry.

The MR mode is used in the nominal regulation mode (Run)
The LPR mode is used in Stop mode.
The power-down mode is used in Standby mode: the regulator output is in high
impedance, and the kernel circuitry is powered down thus inducing zero consumption.
