Software Reset

After an interruption in protocol, power loss or system Reset, any two‑wire device can be protocol reset

by clocking SCL until SDA is released by the EEPROM and goes high. The number of clock cycles until

SDA is released by the EEPROM will vary. The software Reset sequence should not take more than nine

dummy clock cycles. Once the software Reset sequence is complete, new protocol can be sent to the

device by sending a Start condition followed by the protocol. Refer to Figure 5-2 for an illustration.

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 Power-Up Requirements and Reset Behavior).
