Chapter 16 Freescale’s Scalable Controller Area Network (S12MSCANV3)
16.2
The MSCAN uses two external pins.
16.2.1
RXCAN is the MSCAN receiver input pin.
16.2.2
TXCAN is the MSCAN transmitter output pin. The TXCAN output pin represents the logic level on the
CAN bus:
16.2.3
A typical CAN system with MSCAN is shown in
to the CAN bus lines through a transceiver device. The transceiver is capable of driving the large current
needed for the CAN bus and has current protection against defective CAN or defective stations.

0 = Dominant state
1 = Recessive state
RXCAN — CAN Receiver Input Pin
TXCAN — CAN Transmitter Output Pin
CAN System
On MCUs with an integrated CAN physical interface (transceiver) the
MSCAN interface is connected internally to the transceiver interface. In
these cases the external availability of signals TXCAN and RXCAN is
optional.
