The content of the status register reflects the status of the CAN controller. The status register appears to the CPU as a
read only memory.

e.g. to transmit a more urgent message before. A transmission already in progress is not stopped. In order to see if
the original message has been either transmitted successfully or aborted, the transmission complete status bit
should be checked. This should be done after the transmit buffer status bit has been set to logic 1 or a transmit
interrupt has been generated.
It should be noted that a transmit interrupt is generated even if the message was aborted because the transmit buffer
status bit changes to ‘released’.
