HcRhPortStatus[1:4] register (address: value read from func0 or func1 of
address 10H
+
54H)
The HcRhPortStatus[1:4] register is used to control and report port events on a
per-port basis. NumberDownstreamPorts represents the number of HcRhPortStatus
registers that are implemented in hardware. The lower word is used to reflect the port
status, whereas the upper word reflects the status change bits. Some status bits are
implemented with special write behavior. If a transaction (token through handshake)
is in progress when a write to change port status occurs, the resulting port status
change is postponed until the transaction completes. Reserved bits should always be
written logic 0. The bit allocation of the register is given in
Table 84
.

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 POCI
(PortOverCurrentIndicator) bit. The HCD can write logic 1 to clear
this bit. Writing logic 0 has no effect.
