C-bus serial interface
I
2
C-bus uses two wires (SDA and SCL) to transfer information between devices
connected to the bus, and it has the following features:
Bidirectional 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

C-bus may be used for test and diagnostic purposes.
A typical I

C-bus configuration is shown in
Figure 8
. The P89LPC924/925 device
provides a byte-oriented I

C-bus interface that supports data transfers up to 400 kHz.
