This Multi-master IIC (MMIIC) Interface is designed for internal serial
communication between the MCU and other IIC devices. A hardware
circuit generates "start" and "stop" signal, while byte by byte data
transfer is interrupt driven by the software algorithm. Therefore, it can
greatly help the software in dealing with other devices to have higher
system efficiency in a typical digital monitor system.
This module not only can be applied in internal communications, but can
also be used as a typical command reception serial bus for factory setup
and alignment purposes. It also provides the flexibility of hooking
additional devices to an existing system for future expansion without
adding extra hardware.
