Operation
1.
Start condition
A start condition starts by changing the SDA line from “H” to “L” while the SCL line is “H”. Input a start condition first
when inputting a command via I
2C-bus interface.
2.
Stop condition
A stop condition starts by changing the SDA line from “L” to “H” while the SCL line is “H”. Input a stop condition in the
end when inputting a command via I
2C-bus interface.

Data transfer
The S-7750C loads data in the SDA line at a rising edge of the SCL line.
Change the SDA line while the SCL line is “L” during the data transmission.
If changing the SDA line while the SCL line is “H”, the S-7750C goes in the start or stop condition status.
