Description
On write—Clear Remote Wakeup Enable:
0 — No effect
1 — Clears DRWE (Device Remote Wakeup Enable)
-
Over Current Indicator Change: This bit is set by hardware when a
change has occurred to the OCI bit of this register.
0 — No effect
1 — The HCD clears this bit
On read—Local Power Status Change: The Root Hub does not support
the local power status feature. Therefore, this bit is always logic 0.
On write—Set Global Power: In global power mode
(Power Switching Mode = logic 0), logic 1 is written to this bit to turn on
power to all ports (clear Port Power Status). In per-port power mode, it sets
Port Power Status only on ports whose Port Power Control Mask bit is not
set. Writing logic 0 has no effect.
On read—Device Remote Wakeup Enable: This bit enables bit Connect
Status Change (CSC) as a resume event, causing a state transition from
USBSUSPEND to USBRESUME and setting the Resume Detected
interrupt.
0 — CSC is not a remote wake-up event
1 — CSC is a remote wake-up event
On write—Set Remote Wakeup Enable: Writing logic 1 sets DRWE
(Device Remote Wakeup Enable). Writing logic 0 has no effect.
-
Over Current Indicator: This bit reports overcurrent conditions when
global reporting is implemented. When set, an overcurrent condition exists.
When cleared, all power operations are normal. If the per-port overcurrent
protection is implemented, this bit is always logic 0.
On read—Local Power Status: The Root Hub does not support the local
power status feature. Therefore, this bit is always read as logic 0.
On write—Clear Global Power: In global power mode
(Power Switching Mode = logic 0), logic 1 is written to this bit to turn off
power to all ports (clear Port Power Status). In per-port power mode, it
clears Port Power Status only on ports whose Port Power Control Mask bit
is not set. Writing logic 0 has no effect.
