The FIFO identifier rejection register defines a user specified sequence
of bits with which the incoming identifier is compared. This determines
whether the message is rejected by the FIFO. Only a hard reset will clear
the register.
The FIDRJ register can only be written if the SFTRES bit in the Module
Configuration register is set.
The identifier rejection mask register specifies which of the
corresponding bits in the identifier rejection register are relevant for
rejection filtering. A cleared bit in this register indicates that the
corresponding bit in the identifier rejection register must be the same as
the incoming identifier bit, before a match will be detected. The message
will be rejected by the FIFO if all such bits match. If a bit is set, it indicates
that the state of the corresponding bit in the identifier rejection register
will not affect whether or not the message is rejected by the FIFO. Only
a hard reset will set the register.
