Functional Description
Data Sheet
99
V1.1, 2009-08
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 32 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 2 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 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.
– Static Allocation Commands offer compatibility with TwinCAN applications, which
are not list based.
Advanced Interrupt Handling:
– Up to 8 interrupt output lines are available. Most interrupt requests can be
individually routed to one of the 8 interrupt output lines.
– Message postprocessing notifications can be flexibly aggregated into a dedicated
register field of 64 notification bits.
