TRISTATE_BIT(9)

💖 TRISTATE_BIT 💖

okay bestie come CLOSE, because this is one of those HAL components that sounds fancy but is literally just a vibe gate 🚪✨ it lives in the HAL Component manual, section 9, and it's called tristate_bit. the whole point? put a signal on an I/O pin only when you say so — exactly like a tristate buffer in electronics, no cap 🧚

✨ NAME ✨

tristate_bit — Place a signal on an I/O pin only when enabled, similar to a tristate buffer in electronics

like. it's giving "floating until you let me speak" energy 💅

---

🌸 SYNOPSIS 🌸

loadrt tristate_bit [count=N|names=name1[,name2...]]

you either ask for count=N of them or you hand-name them with names=name1[,name2...], pick your fighter 🫶

---

🔥 FUNCTIONS 🔥

• tristate-bit.N — If enable is TRUE, copy in to out.

that's it. that's the whole function. main character behavior honestly 👑

---

🎀 PINS 🎀

• tristate-bit.N.in bit in — Input value
• tristate-bit.N.out bit io — Output value
• tristate-bit.N.enable bit in — When TRUE, copy in to out

so the enable pin is the bouncer at the door 💀 no TRUE, no copy, the out just sits there. when it flips TRUE? in walks straight through to out. iconic. periodt. 🌈
