MSCAN Controller (MSCAN08)
External Pins
The MSCAN08 uses two external pins, one input (RxCAN) and one
output (TxCAN). The TxCAN output pin represents the logic level on the
CAN: 0 is for a dominant state, and 1 is for a recessive state.
A typical CAN system with MSCAN08 is shown in Figure 1.

Figure 1. The CAN System
Each CAN station is connected physically to the CAN bus lines through
a transceiver chip. The transceiver is capable of driving the large current
needed for the CAN and has current protection against defected CAN or
defected stations.
