transition for the addressed section(s) or, more in general, react to the sent command
accordingly. Refer to Figure 7, Table 8 and Table 9 for details about the Set VID command.
L6740L 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.
