PIC18F2480/2580/4480/4580
REGISTER 23-14: RXB1CON: RECEIVE BUFFER 1 CONTROL REGISTER (CONTINUED)
REGISTER 23-15: RXBnSIDH: RECEIVE BUFFER n STANDARD IDENTIFIER REGISTERS,
DS39637A-page 290
bit 7-0
bit 2-0
Mode 0:
FILHIT2:FILHIT0: Filter Hit bits
These bits indicate which acceptance filter enabled the last message reception into
Receive Buffer 1.
111 = Reserved
110 = Reserved
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), only possible when RXB0DBEN bit is set
000 = Acceptance Filter 0 (RXF0), only possible when RXB0DBEN bit is set
Mode 1, 2:
FILHIT2:FILHIT0 Filter Hit bits <2:0>
These bits, in combination with FILHIT<4:3>, indicate which acceptance filter enabled the
message reception into this receive buffer.
01111 = Acceptance Filter 15 (RXF15)
01110 = Acceptance Filter 14 (RXF14)
...
00000 = Acceptance Filter 0 (RXF0)
