8.19 I2C-bus serial interface
I2C-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 I2C-bus may be used for test and diagnostic purposes.
A typical I2C-bus conguration is shown in Figure 8. The P89LPC920/921/922/9221
device provides a byte-oriented I2C-bus interface that supports data transfers up to
400 kHz.
