The SC18IS602/603 device provides a byte-oriented I

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

C-bus master is sending data. At no time does the SC18IS60x act as an I
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
