💖 NAME 💖

ps3_write_ctr — Write counter. Short, sweet, iconic.

---

🎀 SYNOPSIS 🎀

void ps3_write_ctr (u32 cpu , u32 ctr , u32 val );

---

🦋 ARGUMENTS 🦋

Okay bestie, the manual is literally giving us -- undescribed -- for every single one of these, so I’m not gonna invent lore:

• cpu — -- undescribed -- 🙈
• ctr — -- undescribed -- 🙈
• val — -- undescribed -- 🙈

No cap, that’s all it says. We move.

🌸 DESCRIPTION 🌸

So this one writes 16 or 32 bits depending on the current size of the counter. That’s the whole vibe.

And real talk: Counters 4, 5, 6 & 7 are always 16 bit. Periodt.
