5.6.2 Features
The I²C bus uses two wires (SDA and SCL) to transfer information between devices connected to
the bus. The main features of the bus are:
z Master/Slave up to 1Mbit/s
z Bidirectional data transfer between masters and slaves
z Multi-master bus (no central master)
z Arbitration between simultaneously transmitting masters without corruption of serial
data on the bus
z Serial clock synchronization allows devices with different bit rates to communicate via
one serial bus
z Serial clock synchronization can be used as a handshake mechanism to suspend and
resume serial transfer
z Built-in a 14-bit time-out counter will request the I²C interrupt if the I²C bus hangs up
and timer-out counter overflows.
z External pull-up are needed for high output
z Programmable clocks allow versatile rate control
z Supports 7-bit addressing mode
z I²C-bus controllers support multiple address recognition ( Four slave address with
mask option)
