C-bus uses two wires (SDA and SCL) to transfer information between devices
C-bus serial interface
Bi-directional data transfer between masters and slaves
Multimaster bus (no central master)
Arbitration between simultaneously transmitting masters without corruption of
serial data on the bus
Serial clock synchronization allows devices with different bit rates to communicate
via one serial bus
Serial clock synchronization can be used as a handshake mechanism to suspend
and resume serial transfer
The I
