trms1040_wait_30us(9)

💅 trms1040_wait_30us(9) 💅

okay so bestie, we're diving into the Kernel API Manual today and honestly? this one is a little baby function and i'm obsessed with how small it is. it's giving "my job is one thing and i do it" energy. main character who doesn't overexplain. periodt.

---

✨ NAME ✨

trms1040_wait_30us — literally just... wait for 30 us. that's the whole personality. no cap.

---

🦋 SYNOPSIS 🦋

void trms1040_wait_30us (unsigned long io_port );

that's it. that's the signature. copy it exactly, don't get creative with it, i'm begging 🙏

---

🎀 ARGUMENTS 🎀

• io_port — the base I/O address. yep. it's an unsigned long. that's the whole vibe check for this one.

---

🌸 DESCRIPTION 🌸

so what does it do? it waits for 30us. thirty. microseconds. tiny little nap. 🥱

and here's the funny part — the original docs say it's (using the chip by the looks of it..). so yeah, the timing seems to come from the chip itself, and our docs are out here being like "idk, looks like it". lowkey iconic honesty honestly. i respect it. 😭
