5. Read operation
When the S-7750C receives the 7-bit device address and the Read / Write instruction code “1” after receiving a start
condition, it generates an acknowledgment signal.
Next, 8-bit data is output from the S-7750C synchronizing with the SCL clock.
After that, the master device sends a stop condition, not an acknowledgment signal in order to finish the Read
operation.

6. Write operation
6. 1 Write
When the S-7750C receives the 7-bit device address and the Read / Write instruction code “0” after receiving a start
condition, it generates an acknowledgment signal.
Next, after it receives the 8-bit word address and generates an acknowledgment signal, it receives a stop condition to
finish the Write command.
In the Write operation to the E
2PROM, the Write operation starts with a stop condition, the S-7750C finishes it after
the period to Write (max. 5 ms) has elapsed. During Write to the E
2PROM, all operations are inhibited to be performed
and the S-7750C does not send back any acknowledgment signals for command inputs.

Remark
Users are not necessary to input data (8-bit) and the next acknowledgment for the reload command, the
switching access to register / E
2PROM command. If inputting data in this timing, data is regarded as
dummy, the next acknowledgement signal is generated.
