Description
On read, Port Reset Status: When this bit is set by a write to Set Port
Reset, port reset signaling is asserted. When reset is completed and PRSC
is set, this bit is cleared.
0 — Port reset signal is inactive
1 — Port reset signal is active.
On write, Set Port Reset: The HCD can set the port reset signaling by
writing logic 1 to this bit. Writing logic 0 has no effect. If CCS is cleared, this
write does not set PRS (Port Reset Status) but instead sets CCS. This
informs the driver that it attempted to reset a disconnected port.
On read, Port Overcurrent Indicator: This bit is valid only when the Root
Hub is configured to show overcurrent conditions are reported on a per-port
basis. If the per-port overcurrent reporting is not supported, this bit is set to
logic 0. If cleared, all power operations are normal for this port. If set, an
overcurrent condition exists on this port.
0 — No overcurrent condition
1 — Overcurrent condition detected.
On write, Clear Suspend Status: The HCD can write logic 1 to initiate a
resume. Writing logic 0 has no effect. A resume is initiated only if PSS (Port
Suspend Status) is set.
