Basics
The I²C (Inter-Integrated Circuit) protocol, referred to as I-squared-C, I-two-C, or IIC) is two wire serial communication protocol for connecting low speed peripherals to a micrcontroller or computer motherboard.
You can go through I²C /TWI Basics tutorials to understand how I²C works.
Registers
TWBR ( TWI Bit Rate Register )
Bits [7:0] – Bit Rate It selects the division factor for the bit rate generator. The bit rate generator is basically a frequency divider. It generates the SCL clock frequency in the Master modes.
