Frame ID — The semantic of this field depends on the message buffer transfer type.
For receive message buffers it is used as a filter value to determine whether or not the message buffer is used
for reception of a message received in a slot with the slot ID equal to FID.
For a transmit message buffer it is used to determine the slot in which the message in this message buffer will
be transmitted.

If at least one message buffer assigned to a certain slot is assigned to both
channels, then all message buffers assigned to this slot have to be assigned
to both channels. Otherwise, the message buffer configuration is illegal and
the result of the message buffer search is not defined.
