IWR1642: How to read UART RX data in interrupt mode?

Part Number: IWR1642

Hello team,

Customer wants to read UART RX data in interrupt mode? How to setup the ISR for UART RX?

In the SDK, I didnot found any UART read callback function.

Customer wants to receive a unknow length data from UART, then process it. But if he setup a high prority task and read data from UART, he will always get one byte. do we have any method to use it in general ISR mode?

Thanks.
