interrupt.h(3avr)

✨ NAME ✨

interrupt.h

okay bestie, pull up a chair because this one is literally the blueprint for talking to your microcontroller's interrupt system 💅

---

🎀 SYNOPSIS 🎀

✨ Macros ✨

🔥 Global manipulation of the interrupt flag 🔥

so the global interrupt flag lives rent-free in the I bit of the status register (SREG), that's just the facts no cap 🫶

manipulating interrupts lowkey requires you to pay attention to atomic access to objects that could get altered by code running inside an interrupt context — peep <util/atomic.h> for that one 😭

and also!! interrupts are frequently getting disabled for stretches of time so certain operations can happen without being disturbed. for all the deets on that, go look at Problems with reordering code, because there's stuff you have to keep in mind about compiler optimizations 🧚

🦋 Macros for writing interrupt handler functions 🦋

#define ISR(vector,  attributes)
#define SIGNAL(vector)

🌸 ISR attributes 🌸

and that's the whole page, bestie!! this one's from AVR-LibC, Version 2.2.1 🎀 the manpage title is interrupt.h(3avr) and it's your girl AVR-LibC holding it down. periodt 💖🦋🌸
