In dual supply configuration, the power up sequence must be carefully managed to ensure a
safe startup of the device in all conditions.
The power up sequence must ensure that the internal logic is safely powered when the internal
reset (Power On Reset) is released and that the internal Flash logic is safely powered when the
CPU fetch the first instructions.
