Unimplemented: Read as ‘0’
FLC4:FLC0: Filter Length Count bits
Mode 0:
Not used; forced to ‘00000’.
00000-10010 = 0
If DLC3:DLC0 = 0000 No bits will be compared with incoming data bits
If DLC3:DLC0 = 0001 Up to 8 data bits of RXFnEID<7:0>, as determined by FLC2:FLC0, will
If DLC3:DLC0 = 0010 Up to 16 data bits of RXFnEID<15:0>, as determined by FLC3:FLC0,
If DLC3:DLC0 = 0011 Up to 18 data bits of RXFnEID<17:0>, as determined by FLC4:FLC0,

18 bits are available for standard data byte filter. Actual number of bits
used depends on DLC3:DLC0 bits (RXBnDLC<3:0> or BnDLC<3:0> if
configured as RX buffer) of message being received.
