Bits 31:0 FB[31:0]: Filter bits
Filter bank i register x (CAN_FiRx) (i=0..27 in connectivity line devices,, x=1,
2)
Address offsets: 0x240..0x31C
Reset value: undefined
In connectivity line devices there are 28 filter banks, i=0 .. 27, in other devices there are 14
filter banks i = 0 ..13. Each filter bank i is composed of two 32-bit registers, CAN_FiR[2:1].
This register can only be modified when the FACTx bit of the CAN_FAxR register is cleared
or when the FINIT bit of the CAN_FMR register is set.
In all configurations:
Depending on the scale and mode configuration of the filter the function of each register can
differ. For the filter mapping, functions description and mask registers association, refer to
Section 22.7.4: Identifier filtering on page
A Mask/Identifier register in mask mode has the same bit mapping as in identifier list
mode.
For the register mapping/addresses of the filter banks please refer to the

Identifier
Each bit of the register specifies the level of the corresponding bit of the expected identifier.
0: Dominant bit is expected
1: Recessive bit is expected
Mask
Each bit of the register specifies whether the bit of the associated identifier register must
match with the corresponding bit of the expected identifier or not.
0: Don’t care, the bit is not used for the comparison
1: Must match, the bit of the incoming identifier must have the same level has specified in
the corresponding identifier register of the filter.
