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 00002 will show if programming the lower address

boot block is locked out while reading location FFFF2 will

do so for the upper boot block. If the data is FE, the corre-

sponding block can be programmed; if the data is FF, the

program lockout feature has been activated and the corre-

sponding block cannot be programmed. The software

product identification exit mode should be used to return to

standard operation.
