Note 1:
bit 7
Legend:
R = Readable bit
-n = Value at POR
bit 7-0
SID10
R-x
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 buffer will be considered full.
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)
SID10:SID3: Standard Identifier bits (if EXID (RXBnSIDL<3>) = 0)
Extended Identifier bits EID28:EID21 (if EXID = 1).
