USER’S MANUAL
This section is an overview of the TouCAN module. Refer to D.10 TouCAN Module
for information concerning TouCAN address map and register structure.
The TouCAN module is a communication controller that implements the controller
area network (CAN) protocol, an asynchronous communications protocol used in au-
tomotive and industrial control systems. It is a high speed (1 Mbit/sec), short distance,
priority based protocol which can communicate using a variety of mediums (for exam-
ple, fiber optic cable or an unshielded twisted pair of wires). The TouCAN supports
both the standard and extended identifier (ID) message formats specified in the CAN
protocol specification, revision 2.0, part B.
The TouCAN module contains 16 message buffers, which are used for transmit and
receive functions. It also contains message filters, which are used to qualify the re-
ceived message IDs when comparing them to the receive buffer identifiers.
Figure 13-1 shows a block diagram of the TouCAN.
