Standby Mode:
The AT24C16C features a low-power standby mode which is enabled:
Upon power-up.
After the receipt of the Stop Condition and the completion of any internal operations.
2-wire Software Reset:
After an interruption in protocol, power loss or system reset, any 2-wire part can be
reset by following these steps:
1.
Create a Start Condition (if possible).
2.
Clock nine cycles.
3.
Create another Start Condition followed by Stop Condition as shown below.
The device should be ready for the next communication after above steps have been completed. In the event
that the device is still non-responsive or remains active on the SDA bus, a power cycle must be used to reset
