Description
PortSuspendStatusChange: This bit is set when the full resume
sequence has been completed. This sequence includes the 20 s
resume pulse, LS EOP, and 3 ms resynchronization delay. The
HCD writes a logic 1 to clear this bit. Writing a logic 0 has no
effect. This bit is also cleared when ResetStatusChange is set.
0 — resume is not complete
1 — resume is complete
PortEnableStatusChange: This bit is set when hardware events
cause bit PortEnableStatus to be cleared. Changes from HCD
writes do not set this bit. The HCD writes a logic 1 to clear this bit.
Writing a logic 0 has no effect.
0 — no change in PortEnableStatus
1 — change in PortEnableStatus
ConnectStatusChange: This bit is set whenever a connect or
disconnect event occurs. The HCD writes a logic 1 to clear this bit.
Writing a logic 0 has no effect. If CurrentConnectStatus is cleared
when a SetPortReset, SetPortEnable, or SetPortSuspend write
occurs, this bit is set to force the driver to reevaluate the
connection status since these writes should not occur if the port is
disconnected.
0 — no change in CurrentConnectStatus
1 — change in CurrentConnectStatus
Remark: If bit DeviceRemovable[NDP] is set, this bit is set only
after a Root Hub reset to inform the system that the device is
connected.
reserved
(read) LowSpeedDeviceAttached: This bit indicates the speed of
the device connected to this port. When set, a low-speed device is
connected to this port. When clear, a full-speed device is
connected to this port. This field is valid only when the
CurrentConnectStatus is set.
0 — full-speed device attached
1 — low-speed device attached
(write) ClearPortPower: The HCD clears bit PortPowerStatus by
writing a logic 1 to this bit. Writing a logic 0 has no effect.
