Product data sheet
8.21 I
The I
connected to the bus, and it has the following features:
A typical I
device provides a byte-oriented I
400 kHz.

Fig 15. I
C-bus serial interface
Bidirectional data transfer between masters and slaves
Multi master 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
