Description
On write—ClearRemoteWakeupEnable: Writing a logic 1 clears
DeviceRemoveWakeupEnable. Writing a logic 0 has no effect.
reserved
OverCurrentIndicatorChange: 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 logic 1. Writing a logic 0 has no effect.
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 global power mode
(PowerSwitchingMode
power to all ports (clear PortPowerStatus). In per-port power
mode, it sets PortPowerStatus only on ports whose bit
PortPowerControlMask is not set. Writing a logic 0 has no effect.
On read—DeviceRemoteWakeupEnable: This bit enables the bit
ConnectStatusChange as a resume event, causing a state
transition USBSuspend to USBResume and setting the
ResumeDetected interrupt.
0 — ConnectStatusChange is not a remote wake-up event
1 — ConnectStatusChange is a remote wake-up event
On write—SetRemoteWakeupEnable: Writing a logic 1 sets
DeviceRemoveWakeupEnable. Writing a logic 0 has no effect.
reserved
OverCurrentIndicator: This bit reports overcurrent conditions
when global reporting is implemented. When set, an overcurrent
condition exists. When clear, 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 global power mode
(PowerSwitchingMode
power to all ports (clear PortPowerStatus). In per-port power
mode, it clears PortPowerStatus only on ports whose
bit PortPowerControlMask is not set. Writing a logic 0 has no
effect.
