The control area network (CAN) is a computer network protocol and bus standard designed to allow controllers and devices to communicate with each other. CAN is designed specifically for automotive applications but is also used in other applications. The CAN flexible data-rate (CAN FD) controller provides additional features with higher I/O clock frequencies and more buffering.
The controller is designed to the ISO 11898-1/2015 specification that includes backward compatibility to the CAN 2.0 specification. There are two CAN FD controllers, and both are located within the LPD IOP.
