[ERRATA] [nRF51] TIMER_SHORTS only works with timer interrupt enabled?

That is considered the same internally. If the hardware does not detect the COMPARE0, the _CLEAR task will not occur. Let me know if the issue still appears after adding the workaround.

Cheers,

Chip markings: NRF51822 QFAAH0 1745TF. #73 sounds plausible, thanks, I'll try the workaround (although it didn't look like I was loosing events, it's just the SHORTS->COMPARE0_CLEAR task that wasn't triggered. Or is that just the same internally?)

Hi,

SHORTS shall work regardless of if the interrupt source is set in INTENSET or not.

Maybe you are affected by errata #73? http://infocenter.nordicsemi.com/pdf/nRF51822_pan_v3.3.pdf

Could you post the chip-markings of your device? Should be something similar to N51822 / QFAAH1 / 1515AA.

Best regards,

Håkon
