11.9.1 Overview
The I2C 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 I2C bus standard
- Multi-master operation
- Up to 400kHz data transfer speed
- 7-bit address
- Support two slave addresses
- Both master and slave operation
- Bus busy detection
