Description
reserved
Port Test Control: When this field is zero, the port is not operating in a
test mode. A non-zero value indicates that it is operating in test mode
indicated by the value.
Port Indicator Control: Writing to this field has no effect if the
P_INDICATOR bit in the HCSPARAMS register is logic 0.
For a description on how these bits are implemented, refer to Universal
Serial Bus Specification Rev. 2.0 .
Port Owner: This bit unconditionally goes to logic 0 when the configured
bit in the CONFIGFLAG register makes a logic 0 to logic 1 transition. This
bit unconditionally goes to logic 1 whenever the configured bit is logic 0.
Port Power: The function of this bit depends on the value of the PPC (Port
Power Control) field in the HCSPARAMS register.
Line Status: This field reflect the current logical levels of the DP (bit 11)
and DM (bit 10) signal lines.
reserved
Port Reset: Logic 1 means the port is in the reset state. Logic 0 means
the port is not in reset.
Suspend: Logic 1 means the port is in the suspend state. Logic 0 means
the port is not suspended.
Force Port Resume: Logic 1 means resume detected or driven on the
port. Logic 0 means no resume (K-state) detected or driven on the port.
reserved
Port Enabled/Disabled: Logic 1 means enable. Logic 0 means disable.
Connect Status Change: Logic 1 means change in ECCS. Logic 0
means no change.
Current Connect Status: Logic 1 indicates a device is present on the
port. Logic 0 indicates no device is present.
