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
BUKT: Rollover Enable
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 MCP2510).
FILHIT<0>: Filter Hit - indicates which acceptance filter enabled reception of message
1 = Acceptance Filter 1 (RXF1)
0 = Acceptance Filter 0 (RXF0)
