RXM<1:0>: Receive Buffer Operating Mode

= Turn mask/filters off; receive any message

= Receive only valid messages with extended identifiers that meet filter criteria

= Receive only valid messages with standard identifiers that meet filter criteria

= Receive all valid messages using either standard or extended identifiers that meet filter

criteria

bit 4

Unimplemented: Read as '0'

bit 3

RXRTR: Received Remote Transfer Request

= Remote Transfer Request Received

= No Remote Transfer Request Received

bit 2-0

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

W = Writable bit

U = Unimplemented bit, read as ‘0’

-n = Value at POR

’1’ = Bit is set

’0’ = Bit is cleared
