ucb1x00_reg_write(9)

🌸 NAME 🌸

Okay bestie, this is the kernel API manual page for ucb1x00_reg_write(9) — and it does exactly one iconic thing: write a UCB1x00 register. 💅

✨ SYNOPSIS ✨

void ucb1x00_reg_write (struct ucb1x00 *ucb , unsigned int reg ,
       unsigned int val );

🎀 ARGUMENTS 🎀

• ucb — the UCB1x00 structure that describes the chip, periodt.
• reg — the UCB1x00 4-bit register index you're writing to.
• val — the UCB1x00 16-bit value you're writing. 🔥

💅 DESCRIPTION 💅

So here's the vibe: this function writes the UCB1x00 register reg with value val. Simple, clean, main character behavior. ✨

⚠️ Real talk though: the SIB clock must be running for this function to return. That's not a suggestion, bestie — it's literally required for the function to come back. 😭
