bit 7
Unimplemented: Read as '0'
bit 6-5
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
bit 4
Unimplemented: Read as '0'
bit 3
RXRTR: Received Remote Transfer Request
1
= Remote Transfer Request Received
0
= No Remote Transfer Request Received
bit 2
BUKT: Rollover Enable
1
= RXB0 message will rollover and be written to RXB1 if RXB0 is full
0
= Rollover disabled
bit 1
BUKT1: Read Only Copy of BUKT Bit (used internally by the MCP2510).
bit 0
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
W = Writable bit
U = Unimplemented bit, read as ‘0’
-n = Value at POR
’1’ = Bit is set
’0’ = Bit is cleared
x = Bit is unknown
