Circuit operation
(1) Start condition (recognition of start bit)
Before executing any command, when SCL is HIGH, a start condition (start bit) is required to cause SDA to fall from
HIGH to LOW. This IC is designed to constantly detect whether there is a start condition (start bit) for the SDA and
SCL line, and no commands will be executed unless this condition is satisfied.
(See Fig.1 for the synchronized data input / output timing.)
(2) Stop condition (recognition of stop bit)
To stop any command, a stop condition (stop bit) is required. A stop condition is achieved when SDA goes from
LOW to HIGH while SCL is HIGH. This enables commands to be completed.
(See Fig.1 for the synchronized data input / output timing.)
(3) Precautions concerning write commands
In the WRITE mode, the transferred data is not written to the memory unless the stop bit is executed.
