SCL SDA ts2 th2 When data is not being transferred, both SCL and SDA are set in the “H” state. When SCL=SDA is “H,” the start condition is established when SDA is changed from “H” to “L,” and access is started. When SCL is “H,” the stop condition is established when SDA is changed from “L” to “H,” and access is ended. STOP condition START condition SCL SDA ts3 th1 Data transfer and acknowledgement response After the start condition has been established, the data is transferred one byte (8 bits) at a time. Any number of bytes of data can be transferred continuously. Each time the 8-bit data is transferred, the ACK signal is sent from the receive side to the send side. The ACK signal is issued when SDA on the send side is released and SDA on the receive side is set to “L” immediately after fall of the clock pulse at the SCL eighth bit of data transfer to “L.” When the next 1-byte transfer is left in the receive state after sending the ACK signal from the receive side, the receive side releases SDA at the fall of the SCL ninth clock. In the I2C bus, there is no CE signal. In its place, a 7-bit slave address is assigned to each device, and the first byte of transfer is assigned to the command (R/W) representing the 7-bit address and subsequent transfer direction. Note that only write is valid in this IC. The 7-bit address is transferred sequentially starting with MSB, and the eighth bit is set to “L” which indicates a write. In the LV5216CS the slave address is specified as "1110100" Start M S B Start M S B Slave address L S B W A C K M S B Resister address L S B A C K M S B Data L S B A C K Stop L S B W A C K M S B Data1 L S B A C K M S B Data2 L S B A C K Stop SCL SDA (WRITE) SDA (READ) Slave address No.A1968-6/8 LV5216CS Data transfer writing format In the first one byte, the slave address and the Write command are allocated, and the following one byte specifies the register address in the cereal map. The register address is done after the fourth byte be to do the data transfer to the address specified in the register address written in the third byte and the 2nd byte, and to continue data after that and the increment is done by the automatic operation. As a result, a data continuous sending from a specified address becomes possible. However, when the address becomes 3fh, the forwarding address of the following byte becomes 00h.
