Imx6 ESAI TX FIFO empty interrupt - is it possible?

Hello!

Is it possible to generate an interrupt when ESAI TX FIFO gets empty without sdma system usage?

As far as I understand from documentation - TX FIFO Empty event can only trigger an sdma request and it looks like I should write special sdma script to issue an interrupt (interrupt 34?)

May be it is possible to generate an interrupt somehow without using an sdma system?

 

Thanks!
