20.2 Introduction
The MSCAN08 is the specific implementation of the Motorola scalable
controller area network (MSCAN) concept targeted for the Motorola
M68HC08 Microcontroller Family.
The module is a communication controller implementing the CAN 2.0
A/B protocol as defined in the BOSCH specification dated September
1991.
The CAN protocol was primarily, but not exclusively, designed to be
used as a vehicle serial data bus, meeting the specific requirements of
this field: real-time processing, reliable operation in the electromagnetic
interference (EMI) environment of a vehicle, cost-effectiveness and
required bandwidth.
MSCAN08 utilizes an advanced buffer arrangement, resulting in a
predictable real-time behavior, and simplifies the application software.
