The CAN network physical layer consists of a two-wire differential bus, usually twisted pair, and provides a high level of interference immunity. An external CAN transceiver IC is needed to access the bus.
Figure 34-2 shows typical MCAN wiring. Table 34-1 describes the external signals of the MCAN module.
Figure 34-2 MCAN Typical Bus Wiring| Module Signal | I/O | Description | Value at Reset |
|---|---|---|---|
| MCAN_RX | Input | Serial data input from external CAN transceiver. | HiZ |
| MCAN_TX | Output | Serial data output to external CAN transceiver. | HiZ |
