CAN bus informations.

Hardware

CAN bus is available on the APF9328DevFull and APF27Dev (both as an option) and on the APF51Dev (by default).

These boards use Microchip's MCP2515 CAN controller connected to SPI lines of i.MX MPU. Register access is relatively complex due to the need to communicate over SPI interface.
