16.1 Introduction
Freescaleâs scalable controller area network (S12MSCANV3) deï¬nition is based on the MSCAN12
deï¬nition, which is the speciï¬c implementation of the MSCAN concept targeted for the M68HC12
microcontroller family.
The module is a communication controller implementing the CAN 2.0A/B protocol as deï¬ned in the
Bosch speciï¬cation dated September 1991. For users to fully understand the MSCAN speciï¬cation, it is
recommended that the Bosch speciï¬cation be read ï¬rst to familiarize the reader with the terms and
concepts contained within this document.
Though not exclusively intended for automotive applications, CAN protocol is designed to meet the
speciï¬c requirements of a vehicle serial data bus: real-time processing, reliable operation in the EMI
environment of a vehicle, cost-effectiveness, and required bandwidth.
MSCAN uses an advanced buffer arrangement resulting in predictable real-time behavior and simpliï¬ed
application software.
