nand_opcode_8bits(9)

💖 nand_opcode_8bits(9) — Kernel API Manual, bestie 💖

okay so welcome to the Kernel API Manual page for nand_opcode_8bits(9), and honestly it's giving “small function, very specific job.” ✨

🌸 NAME 🌸

nand_opcode_8bits — check if the opcode's address should be sent only on the lower 8 bits 💅

Like, that's the whole assignment: figure out whether the address for this opcode is strictly lower-8-bits territory. no cap. 🎀

🛠️ SYNOPSIS 🛠️

int nand_opcode_8bits (unsigned int command );

🦋 ARGUMENTS 🦋

• command — the opcode you're checking, bestie. 👀 That's the one and only argument, and it's literally described as “opcode to check.”
