AT89C5130A/31A-M
This section describes the 2-wire interface. The 2-wire bus is a bi-directional 2-wire serial com-
munication 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 infor-
mation between the ICs connected to them. The serial data transfer is limited to 400 Kbit/s in
standard mode. Various communication configuration can be designed using this bus.
