SCL SDA ts2 th2 Both SCL and SDA are high when not performing data transfer. When both SCL and SDA are high, changing SDA from high to low generates the START condition and starts access. Changing SDA from low to high while SCL is high generates the STOP condition and ends access. Start condition Stop condition SCL SDA th1 th3 Data transfer and confirmation response After the START condition is generated, data is transferred one byte (8 bits) at a time. Data can be transferred continuously for any number of bytes. The ACK signal is sent from the receiving to the transmitting side each time 8 bits of data are transferred. The transmitting side releases the SDA line immediately after the SCL clock pulse corresponding to the 8th data transfer bit as it falls to Low, and the receiving side then sends the ACK signal by setting SDA Low. After the receiving side sends the ACK signal, if the next byte transfer is still in receive mode, the receiving side releases the SDA line at the falling edge of the 9th SCL clock. The I2C bus does not have a CE signal, so instead a 7-bit slave address is assigned to each device. The first byte of each transfer is assigned to this 7-bit slave address and a command (R/W) indicating the transfer direction of the following data. Note that only Write mode is valid for this IC. The 7-bit address is transferred in order from the MSB, and the 8th bit is Low to indicate Write mode. The LV5217GP slave address is prescribed as “1110101.” Start M S B Slave address L S B W A C K M S B Register address L S B A C K M S B Data L S B A C K Stop SCL SDA 111 010 1 000 000 10 000 100 01 No.A0833-11/12 LV5217GP SANYO Semiconductor Co.,Ltd. assumes no responsibility for equipment failures that result from using products at values that exceed, even momentarily, rated values (such as maximum ratings, operating condition ranges, or other parameters) listed in products specifications of any and all SANYO Semiconductor Co.,Ltd. products described or contained herein.
