NOTES:
4. “MACK”/”SACK”: stands for the acknowledge sent by the master/slave.
5. “A3 ~ A0”: stands for the device addresses sent by the master.
6. “X”: indicates that it is a “0” for testing purpose but physically it is a “don’t care” condition.
7. “I”: stands for the increment operation, SDA held high during active SCL phase (high).
8. “D”: stands for the decrement operation, SDA held low during active SCL phase (high).
