(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.
Sense 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
