The I
the bus. The main features of the bus are:
Features
2
C bus uses two wires (SDA and SCL) to transfer information between devices connected to
Master/Slave up to 1Mbit/s
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
Built-in a 14-bit time-out counter will request the I
and timer-out counter overflows.
External pull-up are needed for high output
Programmable clocks allow versatile rate control
Supports 7-bit addressing mode
