DATA_LENGTH

R

Represents the data length of the transfer

Reserved

20:16

TARGET_ID

Represents the Target/Targets that this transfer is intended for:

- TARGET_ID[0]: Assigned to Virtual Target 0 - TARGET_ID[1]: Assigned to Virtual Target 1 - TARGET_ID[2]: Assigned to Virtual Target 2 - TARGET_ID[3]: Assigned to Virtual Target 3 - TARGET_ID[4]: Assigned to Virtual Target 4

CMD_SIZE

R

Reports if the first data entry in the RX FIFO for the transfer is an encoded command:

- 0x0: No Command Word. The first word from the RX FIFO is the first data word of the transfer. - 0x1: 1 Command Word in the RX FIFO. Only byte 0 is valid. It contains either the HDR CMD code or the CCC code based on the CCC bit in the response. - 0x2: 1 Command Word in the RX FIFO. Only byte 0 and byte 1 are valid. It contains either the HDR CMD code or the CCC code based on the CCC bit in the response in byte 0. It contains the defining byte for the CCC in byte 1. - 0x4: One Command Word in the RX FIFO. All 4 bytes are valid. It contains HDR Bulk Transfer Command words 0, 1, 2 and 3.
