Description
On write, Clear Remote Wake-up Enable:
0 — No effect
1 — Clears DRWE (Device Remote Wake-up Enable)
-
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.
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.
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.
