CAN network physical layer consists of two-wire differential bus, usually twisted pair, and provides high level of interference immunity. External CAN transceiver IC is needed to access a CAN bus by the DCAN.
Figure 26-166 shows an overview of a typical DCAN application.
Table 26-736 describes the external signals of the DCAN1 module .
Module Signal | Device Signal | I/O(1) | Description | Value at Reset |
---|---|---|---|---|
CAN_RX | dcan2_rx | I | Serial data input from external CAN tranceiver | HiZ |
CAN_TX | dcan2_tx | O | Serial data output to external CAN tranceiver | 1 |
Table 26-737 describes the external signals of the DCAN2 module .
Module Signal | Device Signal | I/O(1) | Description | Value at Reset |
---|---|---|---|---|
CAN_RX | dcan1_rx | I | Serial data input from external CAN tranceiver | HiZ |
CAN_TX | dcan1_tx | O | Serial data output to external CAN tranceiver | 1 |
The path from a module pin to device pad(s) is defined at the device I/O logic level. The control module registers assign the specific function to the device pads. For more information on control module settings, see Pad Configuration Registers of Control Module.
