Regulator OFF/internal reset ON
This mode is available only on UFBGA package. It is activated by setting
BYPASS_REG and PDR_ON pins 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 regulator OFF/internal reset ON 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 off.
