bit 7
Unimplemented: Read as '0'
RXM<1:0>: Receive Buffer Operating Mode
11 =Turn mask/filters off; receive any message
10 =Receive only valid messages with extended identifiers that meet filter criteria
01 =Receive only valid messages with standard identifiers that meet filter criteria
00 =Receive all valid messages using either standard or extended identifiers that meet filter
Unimplemented: Read as '0'
RXRTR: Received Remote Transfer Request
1 = Remote Transfer Request Received
0 = No Remote Transfer Request Received
FILHIT<2:0>: Filter Hit - indicates which acceptance filter enabled reception of message
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 if BUKT bit set in RXB0CTRL)
000 = Acceptance Filter 0 (RXF0) (Only if BUKT bit set in RXB0CTRL)
