6 / 14 page MOSA MS6260 Gain And Attenuation Volume Controller IC REV 3 6 www.mosanalog.com Acknowledge During the Acknowledge clock pulse, the master (up) put a resistive HIGH level on the SDA line. The peripheral (audio processor) that acknowledges has to pull-down (LOW) the SDA line during the Acknowledge clock pulse so that the SDA line is in a stable LOW state during this clock pulse. Please refer to the diagram below. SCL SDA MSB Acknowledge 12 3 7 8 9 Start The audio processor that has been addressed has to generate an Acknowledge after receiving each byte, otherwise, the SDA line will remain at the HIGH level during the ninth (9 th) clock pulse. In this case, the master transmitter can generate the STOP information in order to abort the transfer.
