Preliminary
The TwinCAN module permits the connection and autonomous handling of two
independent CAN buses.
• Full-CAN module with 32 message objects, which can be independently assigned to
• The CAN protocol version 2.0B active with standard and extended identifiers can be
• The full CAN baud rate range is supported.
• Scalable FIFO mechanism for reception and transmission in order to improve the real-
• Built-in automatic gateway functionality for data exchange between both CAN buses.
• Powerful interrupt structure, permitting application-specific interrupt generation.
• Remote frames can be monitored.
• Enhanced acceptance filtering (an acceptance mask for each message object).
• A 16 bit frame count / timestamp is implemented for each message object.
• Analyzing mode (no dominant level will be sent) supported.
