Legend:
R = Readable bit
- n = Value at POR
TXBIF: Transmit Buffer Interrupt Flag bit
1 = A message is successfully transmitted
0 = No message was transmitted
TXABT: Transmission Aborted Status bit
1 = Message was aborted
0 = Message was not aborted
TXLARB: Transmission Lost Arbitration Status bit
1 = Message lost arbitration while being sent
0 = Message did not lose arbitration while being sent
TXERR: Transmission Error Detected Status bit
1 = A bus error occurred while the message was being sent
0 = A bus error did not occur while the message was being sent
TXREQ: Transmit Request Status bit
1 = Requests sending a message; clears the TXABT, TXLARB, and TXERR bits
0 = Automatically cleared when the message is successfully sent
RTREN: Automatic Remote Transmission Request Enable bit
1 = When a remote transmission request is received, TXREQ will be automatically set
0 = When a remote transmission request is received, TXREQ will be unaffected
TXPRI1:TXPRI0: Transmit Priority bits
11 = Priority Level 3 (highest priority)
10 = Priority Level 2
01 = Priority Level 1
00 = Priority Level 0 (lowest priority)
