... ST93CS66, ST93CS67 POWER-ON DATA PROTECTION In order to prevent data corruption and inadvertent write operations during power up, a Power On Reset (POR) circuit resets all internal programming circuitry and sets the device in the Write Disable mode. When V reaches its functional value, the CC device is properlyreset (in the Write Disable mode) and is ready to decode and execute an incoming instruction ...
