Stop condition, NJU3730 finishes reading the data.
The slave-address is selected by the condition of the SEL terminal.
Output level of the DO0 to DO2 terminals is selected by the condition of the LSB 3 bits of the output data.
A falling edge of the SDA terminal while the SCL terminal is “H” level is defined as the Start condition. After
