In Mode 1 and 2, there are an additional 10 acceptance
filters, RXF6-RXF15, creating a total of 16 available
filters. RXF15 can be used either as an acceptance
filter or acceptance mask register. Each of these
acceptance filters can be individually enabled or
disabled by setting or clearing RXFENn bit in the
RXFCONn register. Any of these 16 acceptance filters
can be dynamically associated with any of the receive
buffers. Actual association is made by setting appropri-
ate bits in the RXFBCONn register. Each RXFBCONn
register contains a nibble for each filter. This nibble can
be used to associate a specific filter to any of available
receive buffers. User firmware may associate more
than one filter to any one specific receive buffer.
In addition to dynamic filter to buffer association, in
Mode 1 and 2, each filter can also be dynamically asso-
ciated to available acceptance mask registers. FILn_m
bits in the MSELn register can be used to link a specific
acceptance filter to an acceptance mask register. As
with filter to buffer association, one can also associate
more than one mask to a specific acceptance filter.
When a filter matches and a message is loaded into the
receive buffer, the filter number that enabled the
message reception is loaded into the FILHIT bit(s). In
Mode 0 for RXB1, the RXB1CON register contains the
FILHIT<2:0> bits. They are coded as follows:
• 101 = Acceptance Filter 5 (RXF5)
• 100 = Acceptance Filter 4 (RXF4)
• 011 = Acceptance Filter 3 (RXF3)
• 010 = Acceptance Filter 2 (RXF2)
• 001 = Acceptance Filter 1 (RXF1)
• 000 = Acceptance Filter 0 (RXF0)

‘000’ and ‘001’ can only occur if the
RXB0DBEN bit is set in the RXB0CON
register, allowing RXB0 messages to
rollover into RXB1.

The coding of the RXB0DBEN bit enables these three
bits to be used similarly to the FILHIT bits and to distin-
guish a hit on filter RXF0 and RXF1, in either RXB0 or
after a rollover into RXB1.
• 111 = Acceptance Filter 1 (RXF1)
• 110 = Acceptance Filter 0 (RXF0)
• 001 = Acceptance Filter 1 (RXF1)
• 000 = Acceptance Filter 0
If the RXB0DBEN bit is clear, there are six codes cor-
responding to the six filters. If the RXB0DBEN bit is set,
there are six codes corresponding to the six filters plus
two additional codes corresponding to RXF0 and RXF1
filters that rollover into RXB1.
In Mode 1 and 2, each buffer control register contains
5 bits of filter hit bits FILHIT<4:0>. A binary value of ‘0’
indicates a hit from RXF0 and 15 indicates RXF15.
If more than one acceptance filter matches, the FILHIT
bits will encode the binary value of the lowest
numbered filter that matched. In other words, if filter
RXF2 and filter RXF4 match, FILHIT will be loaded with
the value for RXF2. This essentially prioritizes the
acceptance filters with a lower number filter having
higher priority. Messages are compared to filters in
ascending order of filter number.
The mask and filter registers can only be modified
when the PIC18F6585/8585/6680/8680 devices are in
Configuration mode.
