11.10.1 Overview
The I
2
C is one of industrial standard serial communication protocols, and which uses 2 bus lines
Serial Data Line (SDA) and Serial Clock Line (SCL) to exchange data. Because both SDA and SCL
lines are open-drain output, each line needs pull-up resistor. The features are as shown below.
-
Compatible with I
2
C bus standard
-
Multi-master operation
-
Up to 400 KHz data transfer speed
-
7 bit address
-
Support two slave addresses
-
Both master and slave operation
-
Bus busy detection
