This mode is used for 8-bit data transfers with several devices via two lines: a serial clock (SCL) line and a
serial data bus (SDA) line.
This mode complies with the I
“transfer direction specification”, “data”, and “stop condition” data to the slave device, via the serial data bus.
The slave device automatically detects these received state and data by hardware. This function can simplify
