UART block until all data is sent

I need to synchronize sending some data on a UART to some other events. I therefore need to know when the UART have completed sending all data in the SW buffer. I am using the regular UART in Quartus...

    Hi,

    May be you can try to access these uart core control register bits for interrupt. Can refer to this manual (page 145).

    Best Regards

Yes, by bypassing the driver, accessing the device registers directly and using my own interrupt routine I was able to achieve what I needed.
