transition for the addressed section(s) or, more in general, react to the sent command
accordingly. Refer to Figure 6, Table 8 and Table 9 for details about the set VID Command.
L6717 is able to manage individual power OFF for both the sections. The CPU may issue a
serial VID command to power OFF or power ON one Section while the other one remains
powered. In this case, the PWRGOOD signal remains asserted.
