1.2-3 Data transmission format in I
2C bus
I
2C bus generates no CE signals. In place of it each device has a 7bit slave address allocated. The first 1byte is allo-
cated to this 7bit of slave address and to the command (R/W) for which data transmission direction is designated by
the data transmission thereafter. 7bit address is sequentially transmitted from the MSB and 2 and after bytes are
read, when 8bit is “H” and write when “L”.
The slave address of the RS5C372A/B are specified at (0110010).
At the end of data transmission/receiving stop condition is generated to complete transmission. However, if start
condition is generated without generating stop condition, repeated start condition is met and transmission/receiving
data may be continued by setting the slave address again. Use this procedures when the transmission direction
needs to be changed during one transmission.
