The hardware has several functions that make the design flexible and
suitable for other general CAN and LIN applications.

The hardware has the additional circuitry included to allow the
microcontroller to communicate with a PC via its monitor mode. This
enables in-circuit Flash programming and simple debugging to be
performed. Hiware’s MON08 target was used in the application
development.
The MC33399 was used in the demo. This interface is a serial link bus
interface designed to provide bi-directional, half-duplex communication
interfacing in automotive applications. It is similar to the ISO9141
interface, but has additional features specific to the LIN protocol. These
features are wake-up from the LIN bus, wakeup from an external source
and slew rate control to reduce EMI emissions. Refer to the MC33399
data sheet for a detailed description and application diagrams.
In addition to the LIN interface, each node has a CAN physical interface
(MC33388). This is required for the master node, as a simple CAN to LIN
gateway is implemented.
Each node has 8 LEDs (4 red and 4 green) and 2 HEX switches. The
LEDs are driven directly from Port B, configured as output, and used to
demonstrate the LIN protocol and sequencing of messages from the
