Do interrupts set the event register?

[Xenoamor]

In the nRF52840 do the peripheral interrupts (e.g. UART ENDRX) set the event register in the ARM core?

If so is __SEV(); __WFE(); the only way to clear this event?

Hi,

The internal event register is set when you return from an interrupt service routine, so it will be set after you return from the UARTE irq handler. And you must call __WFE() to clear it.
