The MCAN[0-1] modules are hereinafter referred to as MCAN module.
This section describes the MCAN external connections (environment).
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 MCAN.
Figure 12-2100 shows the MCAN typical application.
Table 12-4098 describes the MCAN I/O signals.
Module Pin | Device Level Signal | I/O(1) | Description | Module Pin Reset Value(1) |
---|---|---|---|---|
MCAN[0-1] | ||||
RX | MCAN0_RX | I | Serial data input from external CAN transceiver | HiZ |
TX | MCAN0_TX | O | Serial data output to external CAN transceiver | 1 |
RX | MCAN1_RX | I | Serial data input from external CAN transceiver | HiZ |
TX | MCAN1_TX | O | Serial data output to external CAN transceiver | 1 |
