The code content for the interrupt handlers will reside in Flash, and can be checked on power up like any other part of Flash. But I can't think of any way to test execution of the handlers as part of a self test no.

Dear Kenneth.

Thank you for answer.

I have one more question about stability.

Could I check Interrupt handler? (Is it same to memory check? or Is other way exist?)

Thanks and best regards.

Hi,

We don't have any ECC memory no. It might be possible to create a small bootloader on power up that check RAM and Flash for errors before application start to run, but there is no way to do error correction run time no.
It is possible to for instance setup a GPIOTE task on a pin (e.g. toggle), and then readback the output level on the same pin using nrf_gpio_pin_read() after each time you trigger the GPIOTE task to trigger a toggle. This could serve as a echo test after power up.
