Introduction

This example demonstrates the CAN message transmission and reception in digital loop back mode with the following configuration.

• Classic CAN Message Format.
• Message ID Type is Extended, Msg Id 0xD0, 0xD1, 0xD2, 0xD3, 0xD4.
• MCAN is configured in Polling Mode.
• Arbitration Bit Rate 1Mbps.
• Data Bit Rate 5Mbps.
• FIFO mode is used for Tx and RX to store message in message RAM.

5 Messages are transmitted and received back internally using internal loopback mode. When all the 5 messages received with the id and the data matches with the transmitted one, then the example is completed.
