VPP/ VPEN Protection
When it’s necessary to protect the entire array, global protection can be achieved using
a hardware mechanism. using VPP or VPEN. Whenever a valid voltage is present on VPP
or VPEN, blocks within the main flash array can be erased or programmed. By
grounding VPP or VPEN, blocks within the main array cannot be altered – attempts to
program or erase blocks will fail resulting in the setting of the appropriate error bit in
the Status Register. By holding VPP or VPEN low, absolute write protection of all blocks
in the array can be achieved.
