10.3.4 HcRhPortStatus[1:2] register (R/W [1]:15H/95H, [2]: 16H/96H)
The HcRhPortStatus[1:2] 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 must be postponed until the transaction completes. Reserved bits should
always be written logic 0.
Code (Hex): [1] = 15, [2] = 16 — read
Code (Hex): [1] = 95, [2] = 96 — write

Description

PortResetStatusChange: This bit is set at the end of the 10 ms
port reset signal. The HCD writes a logic 1 to clear this bit. Writing
a 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 Root Hub changes the PortOverCurrentIndicator bit. The
HCD writes a logic 1 to clear this bit. Writing a logic 0 has no
effect.
0 — no change in PortOverCurrentIndicator
1 — PortOverCurrentIndicator has changed
