Overview
The Two-Wire Interface (TWI) is a bi-directional wired-AND bus with only two lines, the clock
(SCL) line and the data (SDA) line. The protocol makes it possible to interconnect up to 128 indi-
vidually addressable devices. Since it is a multi-master bus, one or more devices capable of
taking control of the bus can be connected.
The only external hardware needed to implement the bus is a single pull-up resistor for each of
the TWI bus lines. Mechanisms for resolving bus contention are inherent in the TWI protocol.
PORTC and PORTE each has one TWI. Notation of these peripherals are TWIC and TWIE.
