Description
(Read) Port Reset Status
When this bit is set by writing to Set Port Reset, the port
reset signal is output. This bit is cleared when the PRSC
bit is set upon completion of a reset. When the CCS bit is
cleared, this bit is not set.
0: Port reset signal is not active.
1: Port reset signal is active.
(Write) Set Port Reset
Writing 1 by the host controller driver sets the port reset
(Read) Port Over Current Indicator
This bit is valid only when a root hub is placed in such a
way that an overcurrent condition is reported on the base
of each port. If the overcurrent report at each port is not
supported, this bit is cleared to 0. If this bit is cleared, all
power controls are normal in this port. If this bit is set, an
overcurrent state exists in this port. This bit always
reflects an overcurrent input signal.
0: No overcurrent state.
1: Overcurrent state is detected.
(Write) Clear Suspend Status
Writing 1 by the host controller driver initiates a resume.
When this bit is written to 0, this bit is invalid. If the PSS
