7.1 I
The SC18IS602B acts as a bridge between an I

connected to the bus, and it has the following features:

The SC18IS602B device provides a byte-oriented I
transfers up to 400 kHz. When the I
device will be a slave-transmitter. The SC18IS602B will be a slave-receiver when the

master, however, it does have the ability to hold the SCL line LOW between bytes to
complete its internal processes.

C-bus 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
