4.9  CAN 

The i.MX8M SMARC module features two CAN interfaces based on the MCP2515 stand-alone controller. MCP2515 implements CAN 2.0B protocol 
specification with up to 1Mbps bit rate. Standard and extended data and remote frames are supported. 

Several features are supported (time-triggered protocols, data byte filtering and one-shot mode).
