The Atmel Two-wire Interface Slave (TWIS) 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 I²C or
SMBus compatible master. TWIS is always a bus slave and can transfer sequential or single
bytes.
