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
A15 = 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 is "FF Hex," the boot block programming lockout feature is activated; if the output data "FE Hex," 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.
