Fast switching from low current to normal mode.
The regulator is in ‘low current mode’ when multimedia processor is in sleep
mode. PWREN signal indicates that the multimedia processor is about to switch to
run mode. VDDOK signal indicates to the multimedia processor that all supplies
are in the specified range.
‘Normal mode’ 10 mA full load
‘Power down mode’ or ‘standby mode’ when regulators are switched off and there
is no power consumption (EN_VPLL bit of power control register -
