Initiator Pass-through Status Block Format	Page 5 - 13

CSB Continued Status Block - This bit indicates that the current Status Block is one of several Status Blocks generated because extended Sense Bytes are enabled. Only valid for Pass-through commands issued through Command List.

0 ⇒ Status Block is first (or only) Status Block

1 ⇒ Status Block is one of a series of Status Blocks.

DTG Data Transfer Greater - Indicates when an Initiator Pass-through command completes with more bytes requested by the SCSI device than was specified in the Transfer Count field.

0 ⇒ Data transfer was not greater.

1 ⇒ Data transfer was greater.

DTT Data Transfer Truncated - Indicates when an Initiator Pass-through command completes with fewer bytes transferred than requested in the Transfer Count field.

0 ⇒ Data transfer was not truncated.

1 ⇒ Data transfer was truncated.

RTY Retry - Indicates whether an Initiator Pass-through command required retries to complete.

0 ⇒ No retries were required.

1 ⇒ Retries were required to complete.

ERR Error Status - Identifies when a command, Board-control or Pass- through, completes with an error.

0 ⇒ No error occurred.
