Definitions:
1. “MACK”/“SACK”: stands for the acknowledge sent by the master/slave.
2. “A1 ~ A0”: stands for the device addresses sent by the master.
3. “I”: stands for the increment operation, SDA held high during active SCL phase (high).
4. “D”: stands for the decrement operation, SDA held low during active SCL phase (high).
