Unimplemented: Read as ‘0’
RXM: Receive Buffer Operating Mode bits
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 bit
1 = Remote Transfer Request Received
0 = No Remote Transfer Request Received
BUKT: Rollover Enable bit
1 = RXB0 message will rollover and be written to RXB1 if RXB0 is full
0 = Rollover disabled
BUKT1: Read-only Copy of BUKT bit (used internally by the MCP2515)
FILHIT: Filter Hit bit - indicates which acceptance filter enabled reception of message
1 = Acceptance Filter 1 (RXF1)
0 = Acceptance Filter 0 (RXF0)
Note:

(ADDRESS: 60h)
If a rollover from RXB0 to RXB1 occurs, the FILHIT bit will reflect the filter that accepted
the message that rolled over.
