This register is reset by the UsbReset state.
Description
Read: PortOverCurrentIndicator. This bit reflects the state of the OVRCUR pin dedicated to this port. This field is only
valid if NoOverCurrentProtection is cleared and OverCurrentProtectionMode is set.
0: No over-current condition.
1: Over-current condition.
Write: ClearPortSuspend. Writing a 1 initiates the selective resume sequence for the port. Writing a 0 has no effect.
Read: PortSuspendStatus.
0: Port is not suspended.
1: Port is selectively suspended.
Write: SetPortSuspend. Writing a 1 sets PortSuspendStatus. Writing a 0 has no effect.
Read: PortEnableStatus.
0: Port disabled.
1: Port enabled.
Write: SetPortEnable. Writing a 1 sets PortEnableStatus. Writing a 0 has no effect.
Read: CurrentConnectStatus.
0: No device connected.
1: Device connected.
If DeviceRemoveable is set (not removable) this bit is always 1.
Write: ClearPortEnable. Writing 1 a clears PortEnableStatus. Writing a 0 has no effect.
Reserved. Read/Write 0s.
PortResetStatusChange. This bit indicates that the port reset signal has completed.
0: Port reset is not complete.
1: Port reset is complete.
PortOverCurrentIndicatorChange. This bit is set when OverCurrentIndicator changes. Writing a 1 clears this bit. Writing
a 0 has no effect.
PortSuspendStatusChange. This bit indicates the completion of the selective resume sequence for the port.
0: Port is not resumed.
1: Port resume is complete.
PortEnableStatusChange. This bit indicates that the port has been disabled due to a hardware event (cleared PortEna-
bleStatus).
0: Port has not been disabled.
1: PortEnableStatus has been cleared.
ConnectStatusChange. This bit indicates a connect or disconnect event has been detected. Writing a 1 clears this bit.
Writing a 0 has no effect.
0: No connect/disconnect event.
1: Hardware detection of connect/disconnect event.
If DeviceRemoveable is set, this bit resets to 1.
Reserved. Read/Write 0s.
Read: LowSpeedDeviceAttached. This bit defines the speed (and bud idle) of the attached device. It is only valid when
CurrentConnectStatus is set.
0: Full speed device.
1: Low speed device.
Write: ClearPortPower. Writing a 1 clears PortPowerStatus. Writing a 0 has no effect.
