In case of bit transmission, the signal transition of SDA can not be implemented while SCL is H. If SDA changes while SCL is H, START condition or STOP condition is generated, it is interpreted as control signal. SDA SCL SDA stable state: Data is effective SDA change is Possible ・START condition/STOP condition Data transmission on bus is not implemented while SDA and SCL are H. At this time, if SCL remains to be H and SDA is transited from H to L, then the START condition (S) is attained and so the access is started, and if SCL remains to be H and SDA is transited from L to H, then the STOP condition (P) is attained and so the access is terminated, which is shown below. SDA SCL S P START Condition STOP Condition This device accepts the continuous START condition and the continuous STOP condition. www.rohm.com © 2010 ROHM Co., Ltd. All rights reserved. 8/15 2010.05 - Rev.A BU7839GVW Technical Note ・Acknowledge After START condition is generated, data is transmitted at 8 bits once. After 8 bit transmission, the transmitter opens SDA, and the receiver returns the acknowledge signal with SDA taken as L. SDA output by transmitter Non-acknowledge SDA output by receiver acknowledge SCL 1 S 2 8 9 Clock ulse for acknowledge STARTCONDITION ・Write protocol Write protocol is shown below. Register address is transmitted by 1 byte after device address and write command have been transmitted. Third byte writes the data, which is written in by second byte, into internal register, and for fourth byte and subsequent bytes, the register address is incremented automatically. But, the register address becomes 00h by the transmission of 1 byte after the register address has become the final address (6Ch). The address is incremented after the transmission is over.

For the address after the readout register is finally accessed and the subsequent addresses, the data of the addresses that have been incremented is read out. As the readout of 1 byte after the address has become the final address, 00h is read out. The address is incremented after the transmission is over.

Subsequently, the data of the address that has been incremented is read out. As the readout of 1 byte after the address has become the final address, 00h is read out.
