The user may terminate AAI programming by dropping the WP#/AAI pin to TTL levels (VIH/VIL) as long
as LD# is high and RY/BY# returns to high indicating the completion of the AAI cycle. Software block-
locking will be disabled in AAI mode (all blocks will be write-unlocked). If AAI drops below the Super-
voltage VH before RY/BY# returns to high (and LD# high), the contents of the page may be indetermi-
nate.
