entire array will be write-protected, regardless of
whether the software write-protect register has been
written or not. If the WP pin is set to V
the software write-protect register from being written. If
the WP is tied to V
the status of the software write-protect register for
addresses 00h-7Fh. Addresses 80h-FFh are solely
protected by the WP pin level.
