Notes for software product identification:

(1) Data format: DQ7 − DQ0 (Hex); address format: A14 − A0 (Hex).

(2) A1 − A16 = VIL; manufacture code is read for A0 = VIL; device code is read for A0 = VIH.

(3) The device does not remain in identification mode if power down.

(4) The device returns to standard operation mode.
