MACRO TO UPDATE BITS.(9)

💅 macro to update bits.(9) 💅

the Kernel API Manual, but make it a group chat ✨

okay bestie, before anything else: we're in the Kernel API Manual, and this little cutie is named macro to update bits. — no cap, that's genuinely the whole title. now let's get into it 🫶

🎀 THE VIBE (aka what it does) 🎀

RMW_BITS — it's giving read, modify, update energy. 💅

so like, RMW_BITS is used to read, modify and update bandgap bitfields. that's the whole personality. you hand it a value, and heads up bestie — the value passed will be shifted. ⚠️ not optional, not a vibe, it will be shifted. so factor that in before you go touching bitfields like a main character, fr fr.

🔥 real talk: it reads, it modifies, it updates. the shift is not a rumour. plan accordingly.
