8.5.4.5 Time-Out Function

The TMP114 resets the serial interface if the SCL line is held low by the controller or the SDA line is held low by the TMP114 for 30 ms (typical) between a START and STOP condition. The TMP114 releases the SDA line if the SCL pin is pulled low and waits for a START condition from the controller. To avoid activating the timeout function, maintain a communication speed of at least 1 kHz for the SCL operating frequency. If another device on the bus is holding the SDA pin low, the TMP114 will not reset.
