Unimplemented: Read as '0'
ABTF: Message Aborted Flag
1 = Message was aborted
0 = Message completed transmission successfully
MLOA: Message Lost Arbitration
1 = Message lost arbitration while being sent
0 = Message did not lose arbitration while being sent
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
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)
Unimplemented: Read as '0'

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
