NOTES

1. A START CONDITION AT THE BEGINNING IS DEFINED AS A HIGH-TO-LOW TRANSITION ON SDA WHILE SCLK REMAINS HIGH.

2. A STOP CONDITION AT THE END IS DEFINED AS A LOW-TO-HIGH TRANSITION ON SDA WHILE SCLK REMAINS HIGH.

3. THE MASTER GENERATES THE NO ACKNOWLEDGE AT THE END OF THE READBACK TO SIGNAL THAT IT DOES NOT WANT ADDITIONAL DATA.

4. TEMPERATURE REGISTER MSB DATA AND TEMPERATURE REGISTER LSB DATA ARE ALWAYS SEPARATED BY A LOW ACK BIT.

5. THE R/W BIT IS SET TO A1 TO INDICATE A READBACK OPERATION.
