10.8 CONTROLLER AREA NETWORK (CAN)
10.8.1 Introduction
This peripheral is designed to support serial data
exchanges using a multi-master contention based
priority scheme as described in CAN specification
Rev. 2.0 part A. It can also be connected to a 2.0 B
network without problems, since extended frames
