FUJITSU M3093DG - Manual (Page 78)

a. Allocation length: Byte 4
Specifies the storage area in bytes that the initiator allocates for sense data. If a
0 is set here, sense data is not transferred, but this is not treated as an error.
The target terminates the DATA IN phase when it has transferred either the
bytes of sense data specified in this field or all of effective sense data.
(2) Sense data: DATA IN phase (target Æ initiator)
The target creates sense data if its status is B©00001π (CHECK CONDITION) or if a
BUS FREE error has occurred. This scanner creates sense data when any of the
errors described later is encountered.
The sense data on this scanner is shown in the following illustration.

a. Valid: Byte 0
Indicates whether or not the INFORMATION BYTES field is as specified by
ANSI. This scanner returns B©1π (™specified by ANSI∫ ).
b. Error code: Byte 0
Differentiates between current error or deferred error. This scanner returns
X©70π (™CURRENT ERROR∫ ).
