A.4 Commands

If the actual transfer amount differs from the amount indicated by TL, the target creates the following status and sense data:

∙ Status:

B’00001’ (CHECK CONDITION)

∙Sense key: X’0;’ (NOSENSE)

Sense data (VALID):

 

 

 

 

 

 

Sense data (LI): 1

 

 

 

(Difference in transfer amount)

 

 

 

∙ Sense data (INFORMATION) :

TL indicated transfer amount subtracted by actual

 

 

 

 

transfer amount

Note:

For the read sequence, see Section 4.7.3.
