19.1

Summary

19.1.1

Overview

This document primarily describes the programming interface for the RCAN-ET module. It serves

to facilitate the hardware/software interface so that engineers involved in the RCAN-ET

implementation can ensure the design is successful.

19.1.2

Scope

The CAN Data Link Controller function is not described in this document. It is the responsibility

of the reader to investigate the CAN Specification Document (see references). The interfaces from

the CAN Controller are described, in so far as they pertain to the connection with the User

Interface.

The programming model is described in some detail. It is not the intention of this document to

describe the implementation of the programming interface, but to simply present the interface to

the underlying CAN functionality.

The document places no constraints upon the implementation of the RCAN-ET module in terms of

process, packaging or power supply criteria. These issues are resolved where appropriate in

implementation specifications.

19.1.3

Audience

In particular this document provides the design reference for software authors who are responsible

for creating a CAN application using this module.

In the creation of the RCAN-ET user interface LSI engineers must use this document to

understand the hardware requirements.
