11.1.22 HcRhPortStatus[2:1] register
The HcRhPortStatus[2:1] 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 reects the port status. The upper word
reects 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. Always write logic 0 to the reserved bits. The bit allocation of the register is
given in Table 91.
Table 90.

Description
31
CRWE
On write Clear Remote Wake-up Enable:
0 — No effect
1 — Clears DRWE (Device Remote Wake-up Enable)
30 to 18 reserved

17
CCIC
Overcurrent Indicator Change: This bit is set by hardware when a change has occurred to the OCI
bit of this register.
0 — No effect
1 — The HCD clears this bit.
16
LPSC
On read Local Power Status Change: The root hub does not support the local power status feature.
Therefore, this bit is always logic 0.
On write Set Global Power: In global power mode (Power Switching Mode = 0), logic 1 is written to
this bit to turn on power to all ports (clear Port Power Status). In per-port power mode, it sets Port
Power Status only on ports whose Port Power Control Mask bit is not set. Writing logic 0 has no
effect.
15
DRWE
On read Device Remote Wake-up Enable: This bit enables bit Connect Status Change (CSC) as a
resume event, causing a state transition from USBSUSPEND to USBRESUME and setting the
Resume Detected interrupt.
0 — CSC is not a remote wake-up event.
1 — CSC is a remote wake-up event.
On write Set Remote Wake-up Enable: Writing logic 1 sets DRWE (Device Remote Wake-up
Enable). Writing logic 0 has no effect.
14 to 2

1
OCI
Overcurrent Indicator: This bit reports overcurrent conditions when global reporting is implemented.
When set, an overcurrent condition exists. When cleared, all power operations are normal. If the
per-port overcurrent protection is implemented, this bit is always logic 0.
0
LPS
On read Local Power Status: The root hub does not support the local power status feature.
Therefore, this bit is always read as logic 0.
On write Clear Global Power: In global power mode (Power Switching Mode = 0), logic 1 is written to
this bit to turn off power to all ports (clear Port Power Status). In per-port power mode, it clears Port
Power Status only on ports whose Port Power Control Mask bit is not set. Writing logic 0 has no
effect.
