Description
Device Mode
When set, this bit indicates the controller is operating as a device.
Note:
Full-Speed Device Detected
This read-only bit is set when a full-speed device has been detected on
the port.
Low-Speed Device Detected
This read-only bit is set when a low-speed device has been detected
on the port.
Software should not rely on the value of a reserved bit. To provide
compatibility with future products, the value of a reserved bit should be
preserved across a read-modify-write operation.
Host Mode
This read-only bit is set when the USB controller is acting as a Host.
Software should not rely on the value of a reserved bit. To provide
compatibility with future products, the value of a reserved bit should be
preserved across a read-modify-write operation.
This value is only valid while a session is in progress.
