Functional Description
Summary of Features
• CAN functionality according to CAN specification V2.0 B active.
• Data transfer rate up to 1 Mbit/s
• Flexible and powerful message transfer control and error handling capabilities
• Full-CAN functionality and Basic CAN functionality for each message object
• 32 flexible message objects
– Assignment to one of the two CAN nodes
– Configuration as transmit object or receive object
– Concatenation to a 2-, 4-, 8-, 16-, or 32-message buffer with FIFO algorithm
– Handling of frames with 11-bit or 29-bit identifiers
– Individual programmable acceptance mask register for filtering for each object
– Monitoring via a frame counter
– Configuration for Remote Monitoring Mode
• Up to eight individually programmable interrupt nodes can be used
• CAN Analyzer Mode for bus monitoring is implemented
Note: When a CAN node has the interface lines assigned to Port 4, the segment address
output on Port 4 must be limited. CS lines can be used to increase the total amount
of addressable external memory.

IIC Bus Module
The integrated IIC Bus Module handles the transmission and reception of frames over
the two-line IIC bus in accordance with the IIC Bus specification. The IIC Module can
operate in slave mode, in master mode or in multi-master mode. It can receive and
transmit data using 7-bit or 10-bit addressing. Up to 4 send/receive data bytes can be
stored in the extended buffers.
Several physical interfaces (port pins) can be established under software control. Data
can be transferred at speeds up to 400 kbit/sec.
Two interrupt nodes dedicated to the IIC module allow efficient interrupt service and also
support operation via PEC transfers.
Note: The port pins associated with the IIC interfaces must be switched to open drain
mode, as required by the IIC specification.
