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 12-226 shows the MCAN typical application.
Table 12-203 describes the MCAN I/O signals.
Module Pin | Device Level Signal | I/O(1) | Description | Module Pin Reset Value(1) |
---|---|---|---|---|
MCANi(2) | ||||
RX | MCANi(2)_RX | I | Serial data input from external CAN transceiver | HiZ |
TX | MCANi(2)_TX | O | Serial data output to external CAN transceiver | 1 |
For more information about device level signals (pull-up/down resistors, buffer type, multiplexing and others), see tables Pin Attributes and Pin Multiplexing in the device-specific Datasheet.
