Flags
This byte can be polled to ascertain whether, and in what condition, a command
completed. It has the following format:
TMS Target Mode Status - This bit indicates that this Status Block is for a
Target Mode Response command.
0 ⇒ Status was not the result of a Target Mode Response command.
1 ⇒ Status is a result of a Target Mode Response command.
CSB Continued Status Block - This bit indicates that the current Status
Block is the second of two Status Blocks generated because the SCSI Command
Descriptor Block (CDB) is more than six bytes.
0 ⇒ Status Block is first (or only) Status Block.
1 ⇒ Status Block is second of two Status Blocks.
RTY Retry - Indicates whether this Pass-through command required retries to
complete.
0 ⇒ No retries were required.
1 ⇒ Retries were required to complete.
ERR Error Status - Indicates whether this command completed with an error.
0 ⇒ No error occurred, or if non-zero value exists in the Error field, error was
recoverable.
1 ⇒An error occurred.
CC Command Complete - Indicates whether a command has finished.
0 ⇒Command not complete.
1 ⇒ Command complete.
Error
When the adapter detects an error, this byte contains an error code to describe
the condition. There are special Target Mode error codes that indicate Target
Mode error conditions. These codes are listed along with the other adapter error
codes in Appendix A.
