MSCAN08 Controller (MSCAN08)
12.1 Introduction
The MSCAN08 is the specific implementation of the MSCAN concept targeted for the 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.
