The MultiCAN module contains two Full-CAN nodes operating independently or
exchanging data and remote frames via a gateway function. Transmission and reception
of CAN frames is handled in accordance to 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, where each message object
may be individually allocated to one of the CAN nodes. Besides serving as a storage
container for incoming and outgoing frames, message objects may be combined to build
gateways between the CAN nodes or to setup a FIFO buffer.
The message objects are organized in double chained lists, where each CAN node has
it’s own list of message objects. A CAN node stores frames only into message objects
that are allocated to the list of the CAN node. It only transmits messages from objects of
this list. A powerful, command driven list controller performs all list operations.
The bit timings for the CAN nodes are derived from the peripheral clock (
programmable up to a data rate of 1 MBaud. A pair of receive and transmit pins connects
each CAN node to a bus transceiver.
