Flash Array Protected: Invert Area Bit = 1
Only one range of blocks can be specified in the lower and upper boundary block
address registers. If, after unlocking a range of blocks, the UNLOCK command is again
issued, the new block address range determines which blocks are unlocked. The previ-
ous unlocked block address range is not retained.
The UNLOCK (23h-24h) command is disabled if LOCK is LOW at power-on or if the
device is locked tight (see page 42).
