Advance Information
Functional Description
The bit timings for the CAN nodes are derived from the peripheral clock (f_CAN) and are
programmable up to a data rate of 1 MBaud. A pair of receive and transmit pins connects
each CAN node to a bus transceiver.
Features:
• Compliant to ISO 11898
• CAN functionality according to CAN specification V2.0 B (active)
• Dedicated control registers are provided for each CAN node
• A data transfer rate up to 1 MBaud is supported
• Flexible and powerful message transfer control and error handling capabilities are
implemented
• Advanced CAN bus bit timing analysis and baud rate detection can be performed for
each CAN node via the frame counter
• Full-CAN functionality: A set of 128 message objects can be individually
– allocated (assigned) to any CAN node
– configured as transmit or receive object
– setup to handle frames with 11-bit or 29-bit identifier
– counted or assigned a timestamp via a frame counter
– configured to remote monitoring mode
• Advanced Acceptance Filtering:
– Each message object provides an individual acceptance mask to filter incoming
frames.
– A message object can be configured to accept only standard or only extended
frames or to accept both standard and extended frames.
– Message objects can be grouped into 4 priority classes.
– The selection of the message to be transmitted first can be performed on the basis
of frame identifier, IDE bit and RTR bit according to CAN arbitration rules.
• Advanced Message Object Functionality:
– Message objects can be combined to build FIFO message buffers of arbitrary size,
which is only limited by the total number of message objects.
– Message objects can be linked to form a gateway to automatically transfer frames
between two different CAN buses. A single gateway can link any two CAN nodes.
An arbitrary number of gateways may be defined.
• Advanced Data Management:
– The Message objects are organized in double chained lists.
– List reorganizations may be performed at any time, even during full operation of the
CAN nodes.
– A powerful, command driven list controller manages the organization of the list
structure and ensures consistency of the list.
– Message FIFOs are based on the list structure and can easily be scaled in size
during CAN operation.
