software interrupt number <---> code

I'm using SEGGER's SystemView tool to get some insights on my code. I see which interrupt number is activated, and want to figure out which code actually runs.

looking at nrf52840.h I can see that ISR20 and ISR22 are software interrupts, but that's it.

Is there a way which code actually runs (or which software interrupt is linked to which code)?

Hello,

You need to subtract the ISR number by 16 as the numbers listed in the header start at negative 15. Therefore the ISR22 is the same as GPIOTE_IRQn and ISR20 the same as SPIM1_SPIS1_TWIM1_TWIS1_SPI1_TWI1_IRQn.

Best regards,
