Upon completing a TR the UTC will send back a TR Response to the UDMA-C, and the BCDMA will send back a TR Response. The UTC/ BCDMA TR response format is a single 32-bit word as shown in Table 10-85.

| Bit | Field | Description |
|---|---|---|
| 31:24 | Configuration Specific Flags | These are flag bits that can be specified by the specific UTC/
BCDMA configuration. These bits will remain undefined in the global TR format
to allow for customization requirements that might be required in the specific
UTC/
BCDMA implementation. For UDMA/ BCDMA 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. This field is not supported on BCDMA. |
| 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. |
