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”, “11H” or “15H” or the Reset command “FFH”.
If a command other than “10H”, “11H”, “15H” 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

In order to operate this device stably, after V
The following sequence is necessary because some input signals may not be stable at power-on.
The operation commands are listed in Table 3. Input of a command other than those specified in Table 3 is
During Busy state, do not input any command except 70H, 71H and FFH.
