UCD90160A: PMBUS_CNTRL at POR

Part Number:UCD90160A

If a rail’s On/Off config is set to CONTROL Pin Only, and the PMBUS_CNTRL pin is active when the UCD90160A comes out of Power On Reset (POR), will the enable for the rail be asserted as soon as any other sequence on dependencies associated with the rail are met?

Or is it necessary to make sure the PMBUS_CNTRL pin sees a rising edge (assuming active Hi Polarity) after a POR for the rail enable to be asserted?

Thanks, -John
