minimum value is 1.8 V.
MR is used in nominal regulation mode (Run)
LPR is used in Stop mode
Power-down is used in Standby mode:
The regulator output is in high impedance: the kernel circuitry is powered down,
inducing zero consumption (but the contents of the registers and SRAM are lost).
Regulator OFF/internal reset ON
On UFBGA176 package, REGOFF must be connected to V
The regulator OFF/internal reset ON mode allows to supply externally a 1.2 V voltage
source through V
The following conditions must be respected:
–
–
In this mode, PA0 cannot be used as a GPIO pin since it allows to reset the part of the
1.2 V logic which is not reset by the NRST pin, when the internal voltage regulator in

Otherwise, PA0 should be asserted low externally during POR until V
