Macros
#define	ARM_CAN_UNIT_STATE_INACTIVE (0U)
	Unit state: Not active on bus (initialization)

#define	ARM_CAN_UNIT_STATE_ACTIVE (1U)
	Unit state: Active on bus (can generate active error frame)

#define	ARM_CAN_UNIT_STATE_PASSIVE (2U)
	Unit state: Error passive (can not generate active error frame)

#define	ARM_CAN_UNIT_STATE_BUS_OFF (3U)
	Unit state: Bus-off (can recover to active state)

#define	ARM_CAN_LEC_NO_ERROR (0U)
	Last error code: No error.

#define	ARM_CAN_LEC_BIT_ERROR (1U)
	Last error code: Bit error.

#define	ARM_CAN_LEC_STUFF_ERROR (2U)
	Last error code: Bit stuffing error.

#define	ARM_CAN_LEC_CRC_ERROR (3U)
	Last error code: CRC error.

#define	ARM_CAN_LEC_FORM_ERROR (4U)
	Last error code: Illegal fixed-form bit.
