The Controller Area Network (CAN) module which has been implemented in the Siemens
C167CR microcontrollers allows communication between several stations (CAN nodes) in BASIC-CAN functionality and in FULL-CAN functionality according to CAN specification V2.0B active. This document describes the functionality of the CAN interrupt structure and gives an implementation example of a standard CAN interrupt subroutine.
