(4) FCP SNS LEN VALID [PL:W02/B2/bit1]
When this bit is 1, the field of Length of Sense Information
(FCP_SNS_INFO) is valid and FCP_RSP frame includes the FCP Sense
Information field.
(5) FCP RSP LEN VALID [PL:W02/B2/bit0]
When this bit is 1, the field of Length of Response Information
(FCP_RSP_INFO) is valid and FCP_RSP frame includes the FCP Sense
Information field.
(6) SCSI Status [PL:W02/B2/bit0]

(1) FCP RESID UNDER [PL:W02/B2/bit3]
In case of
FCP_DL (FCP_CNMD) > (transferred data byte velocity based on CDB)
Residual Counter = FCP_DL – (transferred data byte velocity)
(2) FCP RESID OVER [PL:W02/B2/bit2]
In case of
FCP_DL (FCP_CNMD) < (transferred data byte velocity based on CDB)
Residual Counter = (transferred data byte velocity) – FCP_DL
(3) FCP SNS LEN VALID [PL:W02/B2/bit1]
When this bit is 1, the field of Length of Sense Information
(FCP_SNS_INFO) is valid and FCP_RSP frame includes the FCP Sense
Information field.
