.
(write) ClearGlobalPower
In global power mode ( PSM =0), This bit is written to
1 to turn off power to all ports (clear
PPS). In per-port power mode, it clears PPS only on
ports whose PPCM bit is not set. Writing a 0 has no
effect.
0
25 R/W
OCI
Over current indication
This bit reports overcurrent conditions when the global
reporting is implemented. When set, an overcurrent
condition exists. When cleared, all power operations are
normal. If per-port overcurrent protection is
implemented this bit is always 0
0

LPSC
Local power switch change
(read) this bit is always read as 0.
(write) SetGlobalPower
In global power mode ( PSM =0), This bit is
written to 1 to turn on power to all ports (clear
PPS). In per-port power mode, it sets PPS only on ports
whose PPCM bit is not set. Writing a 0 has no effect.
0
27 R/W
OCIC
Over current indication change
This bit is set by hardware when a change has occurred
to the OCI field of this register. The HCD clears this bit
by writing a 1. Writing a 0 has no effect.
0
28 R/W
DRWE
Device remote wakeup enable
This bit enables a ConnectStatusChange bit as a resume
event, causing a USBSUSPEND to USBRESUME state
transition and setting
the ResumeDetected interrupt.
0 = ConnectStatusChange is not a remote wakeup event.
1 = ConnectStatusChange is a remote wakeup event.
