bit 7

bit 0

bit 7

Unimplemented: Read as '0'

bit 6

ABTF: Message Aborted Flag

= Message was aborted

= Message completed transmission successfully

bit 5

MLOA: Message Lost Arbitration

= Message lost arbitration while being sent

= Message did not lose arbitration while being sent

bit 4

TXERR: Transmission Error Detected

= A bus error occurred while the message was being transmitted

= No bus error occurred while the message was being transmitted

bit 3

TXREQ: Message Transmit Request

= Buffer is currently pending transmission

(MCU sets this bit to request message be transmitted - bit is automatically cleared when

the message is sent)

= 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

TXP<1:0>: Transmit Buffer Priority

Highest Message Priority

High Intermediate Message Priority

Low Intermediate Message Priority

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
