1 Introduction

CAN is a multi-master serial protocol that was originally developed for automotive applications. Due to its robustness and reliability, it now finds applications in diverse areas such as Industrial automation, appliances, medical electronics, maritime electronics, and so forth. CAN protocol features sophisticated error detection (and isolation) mechanisms and lends itself to simple wiring at the physical level.

Figure 1 shows the typical implementation of the CAN bus.
