;Very fast receive-routine for the 8xC592. It:

is embedded in the interrupt-handler for the CAN-controller,
8
uses the DMA-logic and

handles up to eight different messages

;(if these have the same leading 8 identier-bits).

12
;To allow for faster receive-routine, it is assumed that all other routines
13
;accessing the CAN-controller, disable the interrupt of the CAN-controller
14
;(IEN0.5) during their execution.
