PRSC
PortResetStatusChange:
This bit is set at the end of the 10 ms
port reset signal. The HCD can write logic 1 to clear this bit.
Writing logic 0 has no effect.
0
port reset is not complete
1
port reset is complete
PortOverCurrentIndicatorChange:
This bit is valid only if
overcurrent conditions are reported on a per-port basis. This bit is
set when the Root Hub changes the PortOverCurrentIndicator
(POCI) bit. The HCD can write logic 1 to clear this bit. Writing
logic 0 has no effect.
19
OCIC
0
no change in PortOverCurrentIndicator (POCI)
1
PortOverCurrentIndicator (POCI) has changed
PortSuspendStatusChange:
This bit is set when the full resume
sequence is complete. This sequence includes the 20 ms resume
pulse, LS EOP and 3 ms re-synchronization delay. The HCD can
write logic 1 to clear this bit. Writing logic 0 has no effect. This bit is
also cleared when ResetStatusChange is set.
18
PSSC
0
resume is not completed
1
resume is completed
PortEnableStatusChange:
This bit is set when hardware events
cause the PortEnableStatus (PES) bit to be cleared. Changes from
the HCD writes do not set this bit. The HCD can write logic 1 to
clear this bit. Writing logic 0 has no effect.
17
PESC
0
no change in PortEnableStatus (PES)
1
change in PortEnableStatus (PES)
ConnectStatusChange:
This bit is set whenever a connect or
disconnect event occurs. The HCD can write logic 1 to clear this
bit. Writing logic 0 has no effect. If CurrentConnectStatus (CCS) is
cleared when a SetPortReset, SetPortEnable or SetPortSuspend
write occurs, this bit is set to force the driver to re-evaluate the
connection status because these writes should not occur if the port
is disconnected.
16
CSC
0
no change in CurrentConnectStatus (CCS)
1
change in CurrentConnectStatus (CCS)
Remark:
If the DeviceRemovable[NDP] bit is set, this bit is set only
after a Root Hub reset to inform the system that the device is
attached.
