bit 7
Unimplemented: Read as '0'
bit 6
ABTF: Message Aborted Flag
1
= Message was aborted
0
= Message completed transmission successfully
bit 5
MLOA: Message Lost Arbitration
1
= Message lost arbitration while being sent
0
= Message did not lose arbitration while being sent
bit 4
TXERR: Transmission Error Detected
1
= A bus error occurred while the message was being transmitted
0
= No bus error occurred while the message was being transmitted
bit 3
TXREQ: Message Transmit Request
1
= Buffer is currently pending transmission
(MCU sets this bit to request message be transmitted - bit is automatically cleared when
the message is sent)
0
= Buffer is not currently pending transmission
(MCU can clear this bit to request a message abort)
bit 2
Unimplemented: Read as '0'
bit 1-0

=
Low Intermediate Message Priority
00
=
Lowest Message Priority
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
