BOOT BLOCK LOCKOUT DETECTION:

A software

method is available to determine whether programming of

either boot block section is locked out. See Software Prod-

uct Identification Entry and Exit sections. When the device

is in the software product identification mode, a read from

location 00002H will show if programming the lower ad-

Device Operation (Continued)

dress boot block is locked out while reading location

1FFF2H will do so for the upper boot block. If the data is

FE, the corresponding block can be programmed; if the

data is FF, the program lockout feature has been activated

and the corresponding block cannot be programmed. The

software product identification exit mode should be used

to return to standard operation.
