Fujitsu 600C Sense data DATA EN phase target → initiator, a Allocation length Byte, a Valid Byte

(a)Allocation length: Byte 4

Specifies the storage area in bytes that tile 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 tile DATA IN phase when it has transferred either the bytes of sense data specified in this field or all of effective sense data.

4.4.4.2Sense data: DATA EN phase (target → initiator)

The target creates sense data if its status is B'00001 ' (CHECK CONDITION) or if a BUS FREE error has occurred. This scanner creates sense data when any of tile errors described later is encountered.

The sense data on this scanner is shown in tile following illustration.

(a)Valid: Byte 0

Indicates whether or not the INFORMATION BYTES field is as specified by ANSI. This scanner returns B'1' ("specified by ANSI").

(b)Error code: Byte 0

Differentiates between current error or deferred error. This scanner returns X'70' ("CURRENT ERROR").

(c)Segment number: Byte 1

This scanner does not support SEGMENT NUMBER. This scanner returns X'00'.
