17.2 Introduction
The msCAN12 is the specific implementation of the Scalable CAN
(msCAN) concept targeted for the Freescale M68HC12 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 only, designed to be used as a
vehicle serial data bus, meeting the specific requirements of this field:
