31:24 | Configuration Specific Flags | These are flag bits that can be specified by the specific UTC configuration. These bits will remain
undefined in the global TR format to allow for
customization requirements that might be required
in the specific UTC implementation. For UDMA channels which are capable of interfacing to endpoint peripherals (or via a PDMA) the format of these flags are as follows: 31:28 error_flags – the error_flags field as is provided across PSI-L 27:24 ps_flags – the ps_flags field as is provided across PSI-L |
23:16 | CMD ID | The Command ID for the TR. This will be sent back with the response for the Channel controller to identify the specific TR. |
15:8 | Reserved | Reserved for Future use |
7:4 | STATUS_INFO | Information that is unique based on the STATUS_TYPE returned |
3:0 | STATUS_TYPE | The completion status of the TR. |
