2-WIRE SOFTWARE RESET: After an interruption in protocol, power loss or system reset, any
two-wire part can be reset by following these steps: (a) Clock up to 9 cycles, (b) Look for SDA
high in each cycle while SCL is high, (c) Create a start condition as SDA is high. The device is
ready for next communication after above steps have been completed.
