Figure 3-7 Block Diagram of MultiCAN Module
The MultiCAN module contains two independently-operating CAN nodes with Full-CAN
functionality that are able to exchange Data and Remote Frames via a gateway function.
Transmission and reception of CAN frames is handled in accordance with CAN
specification V2.0 B (active). Each CAN node can receive and transmit standard frames
with 11-bit identifiers as well as extended frames with 29-bit identifiers.
Both CAN nodes share a common set of message objects. Each message object can be
individually allocated to one of the CAN nodes. Besides serving as a storage container
for incoming and outgoing frames, message objects can be combined to build gateways
between the CAN nodes or to setup a FIFO buffer.
The message objects are organized in double-chained linked lists, where each CAN
node has its own list of message objects. A CAN node stores frames only into message
objects that are allocated to the message object list of the CAN node, and it transmits
only messages belonging to this message object list. A powerful, command-driven list
controller performs all message object list operations.
