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.
