11.2 Introduction
Motorola bus (M bus) is a 2-wire, bidirectional serial bus which provides
a simple, efficient way for data exchange between devices. It is fully
compatible to I2C bus standards and is similar to the MC68HC05T10.
This bus is suitable for applications that require 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 limited to 100 Kbits and the
maximum communication distance and number of devices that can be
connected is limited by the maximum bus capacitance of 400 pF.
The M-bus system is a true multimaster bus including collision detection
and arbitration to prevent data corruption if two or more masters intend
to control the bus simultaneously. This feature provides the capability for
complex applications with multiprocessor control. It may also be used for
rapid testing and alignment of end products by way of external
connections to an assembly-line computer.
