MultiCAN Module
The MultiCAN module contains independently operating CAN nodes with Full-CAN
functionality which are able to exchange Data and Remote Frames using 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.
All 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 set up a FIFO buffer.
Note: The number of CAN nodes and message objects depends on the selected device
type.
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 its own message object list and it transmits only messages
belonging to this message object list. A powerful, command-driven list controller
performs all message object list operations.
