REGISTER 27-14: RXB1CON: RECEIVE BUFFER 1 CONTROL REGISTER (CONTINUED)

bit 2-0

Mode 0:

FILHIT<2:0>: 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:

FILHIT<4:0>: 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)

Note 1: This bit is set by the CAN module upon receiving a message and must be cleared by software after the buffer

is read. As long as RXFUL is set, no new message will be loaded and the buffer will be considered full.
