concepts/compiler-interals/interrupts: Clarify documentation on what interrupt.New does

[soypat]

At no moment in the article is it mentioned what's happening to the function passed to New , should I pass the function to New and also store the function pointer in a hardware register? Or should I do one or the other depending on my target? Does interrupt.New take care of storing the function pointer in the correct hardware register so that NVIC can access it, or does it implement the interrupt via software? In case it needs to store it in the hardware register, then it would have to be implemented in runtime/interrupt, in which case I'd have to check the interrupt functionality I need has been implemented.

This doubt could be solved adding some explanation of what interrupt.New does, which is architecture and processor dependent.

I can work on this if it's alright with y'all
