The Atmel Two-wire Interface Master (TWIM) interconnects components on a unique two-wire
bus, made up of one clock line and one data line with speeds of up to 400 kbit/s, based on a
byte-oriented transfer format. It can be used with any Atmel Two-wire Interface bus serial
EEPROM and I²C compatible device such as a real rime clock (RTC), dot matrix/graphic LCD
controller and temperature sensor, to name a few. TWIM is always a bus master and can
transfer sequential or single bytes. Multiple master capability is supported. Arbitration of the
bus is performed internally and relinquishes the bus automatically if the bus arbitration is lost.
A configurable baud rate generator permits the output data rate to be adapted to a wide range
of core clock frequencies.
