

4.5.1. SetPortControl
Set how the port is turned on and off.
Prototype:
Parameters:
Return Value:
Table 14 lists Port Control values.
If the port control is automatic, the Power Manager automatically turns the port on and off when a PD is connected
and disconnected from the port.
If the port control is forced on, the port's priority is boosted to the forced priority level. This usually results in the port
turning on. However, a forced port cannot cause a critical priority port to turn off in order to turn on the forced port.
If a forced port is granted power, the Power Manager turns on a forced port even if no PD is detected.
If the port control is forced off, the port is unconditionally turned off and held off. A forced-off port is considered to
be temporarily off, while a disabled port is considered to be permanently off.
