Dual filter configuration
In this filter configuration two short filters can be defined.
A received message is compared with both filters to
decide, whether this message should be copied into the
receive buffer or not. If at least one of the filters signals an
acceptance, the received message becomes valid. The bit
correspondences between the filter bytes and the
message bytes depends on the currently received frame
format.
Standardframe:
ifastandardframemessageisreceived,
the two defined filters are looking different. The first filter
compares the complete standard identifier including the
RTRbitandthefirstdatabyteofthemessage.Thesecond
filter just compares the complete standard identifier
including the RTR bit.
For a successful reception of a message, all single bit
comparisons of at least one complete filter have to signal
acceptance. In case of a set RTR bit or a data length code
oflogic 0nodatabyteisexisting. Neverthelessamessage
may pass filter 1, if the first part up to the RTR bit signals
acceptance.
If no data byte filtering is required for filter 1, the four least
significant bits of AMR1 and AMR3 have to be set to
logic 1 (don’t care). Then both filters are working
identically using the standard identifier range including the
RTR bit.
