This field is set by the application and cleared by the OTG host.
The application sets this bit to stop transmitting/receiving data on a channel, even before the
transfer for that channel is complete. The application must wait for the Channel disabled
interrupt before treating the channel as disabled.
This field is set (reset) by the application to indicate that the OTG host must perform a transfer
in an odd frame. This field is applicable for only periodic (isochronous and interrupt)
transactions.
This field selects the specific device serving as the data source or sink.
Indicates the transfer type selected.
This field is set by the application to indicate that this channel is communicating to a low-
speed device.
Indicates whether the transaction is IN or OUT.
Indicates the endpoint number on the device serving as the data source or sink.
Indicates the maximum packet size of the associated endpoint.
