MOTOROLA
The TouCAN module interface to the CAN bus is composed of four pins: CANTX0 and
CANTX1, which transmit serial data, and CANRX0 and CANRX1, which receive serial
data. Figure 13-2 shows a typical CAN system.
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 address space is split into 128 bytes starting at the base ad-
dress, and then an extra 256 bytes starting at the base address +128. The upper 256
are fully used for the message buffer structures. Out of the lower 128 bytes, only part
is occupied by various registers. Refer to D.10 TouCAN Module for detailed informa-
tion on the TouCAN address map and register structure.
