Operation
Start is identified by a high to low transition of the SDA line while the SCL line is stable at high.
Every operation begins from a start condition.
Stop is identified by a low to high transition of the SDA line while the SCL line is stable at high.
When a device receives a stop condition during a read sequence, the read operation is interrupted, and the
device enters standby mode.
When a device receives a stop condition during a write sequence, the reception of the write data is halted,
and the E
