STRUCT ADIN_CLAUSE45_MMD_MAP(9)

💖 struct adin_clause45_mmd_map — like, the NAME section but make it cute ✨

okay so bestie, this is the whole vibe: struct adin_clause45_mmd_map is the little lookup buddy that maps Clause 45 registers over to Clause 22. That's it, that's the whole thing. It's giving translator-extraordinaire and honestly? iconic. 🦋

This page lives in the Kernel API Manual (iykyk) — say hi to your new hyperfixation.

✨ SYNOPSIS ✨

struct adin_clause45_mmd_map {
    int devad;
    u16 cl45_regnum;
    u16 adin_regnum;
};

three fields, no drama, no cap. 📋

🎀 Members 🎀

• devad — the device address, the one you use when you go do a Clause 45 access. it's an int, yeah, don't ask, that's what it is. 💅
• cl45_regnum — the register address as defined by Clause 45. a u16. that's the "before" of the glow-up. ✨
• adin_regnum — the equivalent register address, except this one you can actually reach via Clause 22. a u16 too. that's the "after". 🔥

fr fr the whole point of this struct is: cl45_regnum in, adin_regnum out. the mapping is the moment. 💖
