7.1.1

Startup mode

This state is entered to begin the switching activity (during application's turn-on or exiting

from the low consumption state). The HVSU is involved into the mechanism of VCC

charging; all other peripherals, except the UVLO and logic supply, are turned off to minimize

the startup time.

During this state the CTRL pin is internally pulled to ground.
