HcRhStatus register: bit description
Symbol Description
CRWE
On write—ClearRemoteWakeupEnable: Writing logic 1 clears
DeviceRemoveWakeupEnable (DRWE). Writing logic 0 has no
effect.
-
reserved
CCIC
OverCurrentIndicatorChange: This bit is set by hardware when a
change has occurred to the OverCurrentIndicator (OCI) field of this
register. The HCD clears this bit by writing logic 1. Writing logic 0
has no effect.
LPSC
On read—LocalPowerStatusChange: The Root Hub does not
support the local power status feature. Therefore, this bit is always
read as logic 0.
On write—SetGlobalPower: In the global power mode
(PowerSwitchingMode = 0), logic 1 is written to this bit to turn on
power to all ports (clear PortPowerStatus). In the per-port power
mode, it sets PortPowerStatus only on ports whose
PortPowerControlMask bit is not set. Writing logic 0 has no effect.
DRWE
On read—DeviceRemoteWakeupEnable: This bit enables the
bit ConnectStatusChange as a resume event, causing a state
transition from USBSuspend to USBResume and setting the
ResumeDetected interrupt.

0 — ConnectStatusChange is not a remote wake-up event

On write—SetRemoteWakeupEnable: Writing logic 1 sets
DeviceRemoveWakeupEnable. Writing logic 0 has no effect.
reserved
OverCurrentIndicator: This bit reports overcurrent conditions
when 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
logic 0.
On read—LocalPowerStatus: The Root Hub does not support the
local power status feature. Therefore, this bit is always read as
logic 0.
On write—ClearGlobalPower: In the global power mode
(PowerSwitchingMode = 0), logic 1 is written to this bit to turn off
power to all ports (clear PortPowerStatus). In the per-port power
mode, it clears PortPowerStatus only on ports whose
PortPowerControlMask bit is not set. Writing logic 0 has no effect.
