65.4.2.2 Message type filter register (NAR_TFR)
The MSP can be configured to accept or exclude messages of up to four types, as encoded
in the message TCODE field. The TCODEs which are to be filtered are programmed in the
message type filter register (NAR_TFR) as shown in the following figure. This register
should only be set in the BD NAR because partitioning is not supported in the PD NAR.
