UART LINESTSIT interrupt

hmj

I am looking for a way to generate an interrupt every time, RXD pin changes state. Can I use LINESTSIT interrupt (one of the interrupts in UART settings) for this? If not is there any other interrupt I can use?

Read section 19.3.5.1.1 from the AM335x TRM Rev. O. All UART interrupts and their sources are listed there.

Thanks Biser. I found my answer. To pick the falling edge on RXD pin I can use RXCTSDSRWAKEUPENABLE interrupt explained in 19.5.1.39. I need to test this.
