MUX4(9)

💖 NAME 💖

mux4 — bestie, it picks ONE of four input values and sends it through. That's it, that's the whole vibe. A four-way switcheroo ✨

---

🎀 SYNOPSIS 🎀

loadrt mux4 [count=N|names=name1[,name2...]]

okay so you load it, and you either say how many copies you want with count=N or you name them yourself with names=name1[,name2...] — pick your fighter, don't do both 🫶

---

🌸 FUNCTIONS 🌸

• mux4.N — this one needs a floating-point thread, no cap. It literally will not run in an integer thread, so check your thread type before you come crying to me 😭

---

👑 PINS 👑

• mux4.N.sel0 bit in
• mux4.N.sel1 bit in

ngl these two are the whole decision-making committee 💅 Together, they determine which inN value gets copied over to out. Two bits, four outcomes, main character energy.

• mux4.N.out float out

This one just follows whichever of the inN values the two sel values point at. The way it works:

• sel1=FALSE, sel0=FALSE → out follows in0 🍓
• sel1=FALSE, sel0=TRUE → out follows in1 🌈
• sel1=TRUE, sel0=FALSE → out follows in2 💜
• sel1=TRUE, sel0=TRUE → out follows in3 ⭐

• mux4.N.in0 float in
• mux4.N.in1 float in
• mux4.N.in2 float in
• mux4.N.in3 float in

The four candidates. Four float inputs, all just sitting there waiting to be the chosen one 🧚
