ENUM PRU_IOMEM(9)

🌸 ENUM PRU_IOMEM(9) 🌸

okay bestie, buckle up — this is the enum pru_iomem page from the Kernel API Manual, and it's literally the cheat sheet for PRU core memory/register range identifiers ✨ no cap, that's the whole NAME section, we move 💅

---

✨ SYNOPSIS ✨

here's the whole enum, bestie — copy it exactly, it's giving sacred text 🎀

enum pru_iomem {
    PRU_IOMEM_IRAM ,
    PRU_IOMEM_CTRL ,
    PRU_IOMEM_DEBUG ,
    PRU_IOMEM_MAX

};

like… that's it. four little icons in the list and they all ate 🔥

💖 Constants 💖

these are the squad members, let me introduce you 🫶

• PRU_IOMEM_IRAM — the PRU Instruction RAM range 💾 that's where the instructions live, main character energy fr
• PRU_IOMEM_CTRL — the PRU Control register range 🎛️ the control girlies, we stan
• PRU_IOMEM_DEBUG — the PRU Debug register range 🐛 for when you gotta snoop, iykyk
• PRU_IOMEM_MAX — the manual literally says "just keep this one at the end" 😭 and honestly? respect the bluntness. keep it at the end, bestie, no notes 💀

lowkey important: PRU_IOMEM_MAX is a sentinel-type vibe — the docs say keep it at the end, so keep it at the end 🙈
