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.
