Input interrupt on UART RXD pin

hmj

Hi,

I would like to generate falling edge interrupt from the same RXD pin of one of the UARTs. Is this possible? This means while UART is doing it's job receiving data from serial port, every time the level changes I also get an interrupt.

Cheers,

Hassan

Hi,

Please 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.
