It is supported in hardware for multiple protocols: CAN1.0, CAN2.0, and CANFD. I'm pretty sure there are 3 ports that can be used simultaneously and independently. I only use 2 with CAN1.0.

Edit: By hardware support I mean that a CAN transciever connects to two GPIO pins with access to CAN chip hardware. No SPI interface needed.

Do you need a CAN controller and a CAN transceiver or just a transceiver?
