3.2 Transmit Abort Function
By disabling the use of the transmit/receive FIFO buffer, the messages in the transmit/receive FIFO buffer can be
aborted. Aborting the transmit/receive FIFO buffer aborts all messages in the transmit/receive FIFO buffer, not just the
messages being sent (the transmit/receive FIFO buffer becomes empty (the CFEMP flag in the CFSTSk register is “1”)).
You can check the completion of aborting the transmit/receive FIFO buffer by checking that the transmit/receive FIFO
buffer is empty.
No interrupt is generated when the transmit abort of the transmit/receive FIFO buffer is completed. However, if
aborted during transmission, a transmit/receive FIFO transmission completion interrupt may occur due to transmission
completion. For details, refer to "Figure 2-3 Application example of transmission abort function".
For the transmit abort procedure of the transmit/receive FIFO buffer, refer to "Figure 3-4 Procedure for prohibiting
use of transmit/receive FIFO buffer ".
