transmission has completed. The slave side (transmission side) continues to release the SDA pin so that
the master will be able to generate Stop Condition, after falling edge of the SCL 9bit of clock pulses.

C-Bus has no chip enable signal line. In place of it, each device has a 7bit Slave Address allocated. The
first 1byte is allocated to this 7bit 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 when write “L”.
The Slave Address of the RV5C386A is 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 continue by setting the Slave Address again. Use this procedure when
the transmission direction needs to be change during one transmission.
