This IC has a built-in data transmission interface which utilizes
2 unidirectional buses. In communications, this IC functions as
a slave reception device. Set CS pin to “H” level at the I
serial input communication.
The IC is synchronized with the serial clock (SCL) sent from
the master device and receives the data (SDA). Communica-
tions are controlled from the start/stop states. Also, always in-
put the control byte after attaining the start state.
The below chart shows the start/stop state and control byte
configuration.
