Multi-Master IIC Interface (MMIIC)
14.1 Introduction
The multi-master IIC (MMIIC) interface is a two wire, bidirectional serial bus which provides a simple,
efficient way for data exchange between devices. The interface is designed for internal serial
communication between the MCU and other IIC devices. It has hardware generated START and STOP
signals; and byte by byte interrupt driven software algorithm.
This bus is suitable for applications which need frequent communications over a short distance between
a number of devices. It also provides a flexibility that allows additional devices to be connected to the bus.
The maximum data rate is 100k-bps, and the maximum communication distance and number of devices
that can be connected is limited by a maximum bus capacitance of 400pF.
This MMIIC interface is also SMBus (System Management Bus) version 1.0 and 1.1 compatible, with
hardware cyclic redundancy code (CRC) generation, making it suitable for smart battery applications.
