Acceptance Filter
Upon a reception hit (i.e., a good comparison between the ID+RTR+RB+IDE received
and an ID+RTR+RB+IDE specified while taking the comparison mask into account) the
ID+RTR+RB+IDE received are written over the ID TAG Registers.
ID => IDT0-29
RTR => RTRTAG
RB => RB0-1TAG
IDE => IDE in CANCONCH register
