These registers are available in Mode 1 and 2 only.
Clearing this bit in software while the bit is set will request a message abort.
This bit is automatically cleared when TXREQ is set.
While TXREQ is set or a transmission is in progress, Transmit Buffer registers remain read-only.
These bits set the order in which the Transmit Buffer register will be transferred. They do not alter the CAN
message identifier.
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
TXPRI<1:0>: Transmit Priority bits
11 = Priority Level 3 (highest priority)
10 = Priority Level 2
01 = Priority Level 1
00 = Priority Level 0 (lowest priority)
