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

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)

Note: If a rollover from RXB0 to RXB1 occurs, the FILHIT bit will reflect the filter that accepted

the message that rolled over

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
