The CAN module is a protocol controller that converts
between raw digital data and CAN message packets.
The main functional block of the CAN module is shown
in Figure 2-1 and consists of:
• CAN protocol engine
• Buffers, masks and filters
The module features include:
• Implementation of the CAN protocol
• Double-buffered receiver with two separate
