2-wire Interface (TWI) This section describes the 2-wire interface. In the rest of the section SSLC means Two-
wire. The 2-wire bus is a bi-directional 2-wire serial communication standard. It is
designed primarily for simple but efficient integrated circuit (IC) control. The system is
comprised of two lines, SCL (Serial Clock) and SDA (Serial Data) that carry information
between the ICs connected to them. The serial data transfer is limited to 400Kbit/s in
standard mode. Various communication configuration can be designed using this bus.
Figure 35 shows a typical 2-wire bus configuration. All the devices connected to the bus
can be master and slave.
