Furthermore, the filters can be configured in mask mode or in identifier list mode.
Mask mode
In mask mode the identifier registers are associated with mask registers specifying which
bits of the identifier are handled as “must match” or as “don’t care”.
Identifier list mode
In identifier list mode, the mask registers are used as identifier registers. Thus instead of
defining an identifier and a mask, two identifiers are specified, doubling the number of single
identifiers. All bits of the incoming identifier must match the bits specified in the filter
registers.
Figure 102. Filter bank scale configuration - register organization
Filter bank scale and mode configuration
The filter banks are configured by means of the corresponding CFCRx register. To configure
a filter bank this must be deactivated by clearing the FACT bit in the CFCR register. The filter
scale is configured by means of the FSC[1:0] bits in the corresponding CFCR register, refer
