7.4 TouCAN Architecture
7.4.1 TX/RX Message Buffer Structure
MC68F375
REFERENCE MANUAL
Each CAN station is connected physically to the CAN bus through a transceiver. The
transceiver provides the transmit drive, waveshaping, and receive/compare functions
required for communicating on the CAN bus. It can also provide protection against
damage to the TouCAN caused by a defective CAN bus or a defective CAN station.
The TouCAN module uses a flexible design that allows each of its 16 message buffers
to be designated either a transmit (TX) buffer or a receive (RX) buffer. In addition, to
reduce the CPU overhead required for message handling, each message buffer is
assigned an interrupt flag bit to indicate that the transmission or reception completed
successfully.
