Dear All, I have an question about CAN bus transmit interrupt. I use STM32F303.

In reference manual, it describes when transmit mailbox becomes empty, the interrupt will be triggered.

It also means of that when transmit procedure is completed, the interrupt will be triggered. right?

if yes, what should I do in the ISR(interrupt service routine)? There are no thing need to process due to the transmission is already completed. it seems like of an superfluous ISR.
