3.5 Software Reset
After an interruption in protocol, power loss, or system reset, any 2-wire part can be protocol reset by following
these steps:
1. Create a Start condition (if possible).
2. Clock nine cycles.
3. Create another Start condition followed by a Stop condition as seen in Figure 3-2.
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
the device (see Section 8.6.1, “Device Reset”).
