nRF52840 : UART peripheral receiver FIFO reset

[ACAMP]

Hello:

nRF52840 UART peripheral receiver FIFO reset

Whenever there is a receiving error ( Frame error or Break error or any) , I would like to reset the receiver's FIFO to its power up state, and then re-start reception.

Is there any way to do that ?

Thanks

Are you using UART or UARTE.

There is no reset receiver only feature available, but you could read the RXD register (ignore the read bytes) and reset the EVENT_RXDRDY + clearing ERRORSRC and EVENTS_ERROR should bring back the receiver to power up state.
