This device provide another function to determine the internal programming cycle. If the EEPROM is set to read mode
during the internal programming cycle, I/O6 will charge from â1â to â0â (toggling) for each read. When the internal
programming cycle is finished, toggling of I/O6 will stop and the device can be accessible for next read or program.
Notes: 1. I/O6 beginning state is â1â.
2. I/O6 ending state will vary.
3. See AC read characteristics.
4. Any location can be used, but the address must be fixed.
