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 “1” to “0” (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.
