Functional Description
MultiCAN Features
• CAN functionality conforming to CAN specification V2.0 B active for each CAN node
(compliant to ISO 11898)
• Independent CAN nodes
• Set of independent message objects (shared by the CAN nodes)
• Dedicated control registers for each CAN node
• Data transfer rate up to 1 Mbit/s, individually programmable for each node
• Flexible and powerful message transfer control and error handling capabilities
• Full-CAN functionality for message objects:
– Can be assigned to one of the CAN nodes
– Configurable as transmit or receive objects, or as message buffer FIFO
– Handle 11-bit or 29-bit identifiers with programmable acceptance mask for filtering
– Remote Monitoring Mode, and frame counter for monitoring
• Automatic Gateway Mode support
• 16 individually programmable interrupt nodes
• Analyzer mode for CAN bus monitoring

System Timer
The System Timer consists of a programmable prescaler and two concatenated timers
(10 bits and 6 bits). Both timers can generate interrupt requests. The clock source can
be selected and the timers can also run during power reduction modes.
Therefore, the System Timer enables the software to maintain the current time for
scheduling functions or for the implementation of a clock.
