Legend:
C = Clearable bit
‘1’ = Bit is set
Mode 0:
Unimplemented: Read as ‘0’
Mode 1, 2:
TXBIF: Transmit Buffer Interrupt Flag bit
1 = Transmit buffer has completed transmission of message and may be reloaded
0 = Transmit buffer has not completed transmission of a message
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
Unimplemented: Read as ‘0’
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)
