prohibited. Stored data may be corrupted if an unknown command is entered during the command cycle.
Restriction of command while Busy state
Acceptable commands after Serial Input command “80H”
Execution command “10H” or the Reset command “FFH”.
If a command other than “10H” or “FFH” is input, the Program operation is not performed.
The WP signal is useful for protecting against data corruption at power-on/off. The following timing
The WP signal may be negated any time after the V
