✨ ad4695_enter_advanced_sequencer_mode ✨

okay so bestie, this is a page straight out of the Kernel API Manual and it's literally about putting your ADC into advanced sequencer mode. no cap, it's a whole vibe. let's get into it 💅

🌸 NAME 🌸

ad4695_enter_advanced_sequencer_mode — puts the ADC into advanced sequencer mode 🎀

like, that's the whole job. it shows up, it flips the bits, it leaves. iconic behavior fr fr.

---

🦋 SYNOPSIS 🦋

int ad4695_enter_advanced_sequencer_mode(struct ad4695_state *st, u32 n);

---

💖 ARGUMENTS 💖

• st — the driver state 🫶 you know, the whole context of the thing, the main character of this function.
• n — the number of slots you wanna use. heads up tho: it must be >= 2, <= 128 ⚠️ like, no going under two, no going over a hundred and twenty-eight. that's the range, periodt.

---

🔥 DESCRIPTION 🔥

so here's the tea 🍵 — as per the datasheet, to enable the advanced sequencer you gotta set three things:

• STD_SEQ_EN=0
• NUM_SLOTS_AS=n-1
• CYC_CTRL=0

that's straight from Table 15 in the datasheet, iykyk 📖✨

and then — this is the fun part — setting SPI_MODE=1 triggers the first conversion, using the channel in AS_SLOT0 🔥 like, that's the spark, that's the moment it all starts happening.

ngl the n-1 is doing a lot of heavy lifting here, don't sleep on it 💀

---

🌈 RETURN 🌈

• 0 on success — slay, you did it 👑
• a negative error code on failure — 😭 not the vibe, something went wrong
