Is WDT pause on halt only paused when halted by debugger?

[mk2]

Hi,

In the Product Specification for nrf52840 it´s written that setting CONFIG (0x50C) register to Pause (0) would pause the watchdog while the cpu is halted by a debugger.

My understanding is that this option will not pause the WDT when cpu is halted for other reasons, like initating NVMC operations. I.e WDT can distinguish between halted by debugger and halted by other reasons.

Is my understanding correct?

Hi,

Yes, your understanding is correct, the WDT will only be paused when the CPU has been halted by the debugger, not when it's halted because of a NVMC operation.

Best regards,
