8-bit microcontroller with accelerated two-clock 80C51 core
7.21 I
2
C-bus serial interface
The 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:
Bi-directional 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
2
C-bus may be used for test and diagnostic purposes.
A typical I
2
C-bus configuration is shown in
Figure 13
. The P89LPC932A1 device provides
a byte-oriented I
2
C-bus interface that supports data transfers up to 400 kHz.
