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

criteria

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)

Legend:

R = Readable bit

-n = Value at POR

W = Writable bit

’1’ = Bit is set

U = Unimplemented bit, read as ‘0’

’0’ = Bit is cleared x = Bit is unknown
