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.
