12.5.17.4 Single Filter Configuration
In this filter configuration one long filter (4-byte) could be
defined. The bit correspondences between the filter bytes
and the Message bytes depends on the programmed
Frame Format (see ACF Mode Register).
Single Filter Standard Frame:
If the Standard Frame Format is selected, the complete
Identifier including the RTR bit and the first two data bytes
are used for acceptance filtering. Messages may also be

accepted if there are no data bytes existing due to a set
RTR bit or if there is no or only one data byte because of
the corresponding data length code.
For a successful reception of a message, all single bit
comparisons have to signal acceptance. Note that the 4
least significant bits of AMR1 and ACR1 are not used. In
order to keep compatible with future products these bits
should be programmed to be “don‘t care” by setting
AMR1.3, AMR1.2, AMR1.1 and AMR1.0 to “1”.
