Notes for software product identification/boot block lockout detection:
(1) Data Format: DQ15-DQ8 (Don't Care), DQ7
DQ0 (Hex); Address Format: A14
A0 (Hex)
(2) A1
A16 = V
IL
; manufacture code is read for A0 = V
IL
; device code is read for A0 = V
IH
.
(3) The device does not remain in identification and boot block lockout detection mode if power down.
(4) If the output data in DQ0 = 1, the boot block programming lockout feature is activated; if the output data in DQ0 = 0, the lockout feature is
inactivated and the block can be programmed.
(5) The device returns to standard operation mode.
(6) Optional 1-write cycle (write F0 hex at XXXX address) can be used to exit the product identification/boot block lockout detection.
