Toggle bit
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.
Toggle bit Waveform
Notes: 1. I/O6 beginning state is "1".
2. I/O6 ending state will vary.
3. See AC read characteristics.
4. Any address location can be used, but the address must be fixed.
