parport_ip32_data_reverse(9)

okay so bestie, we're looking at parport_ip32_data_reverse(9) from the Kernel API Manual, and it's giving “enable peripheral-to-host communications” in the most iconic way ✨💅

🌸 NAME 🌸

parport_ip32_data_reverse — enable peripheral-to-host communications 🫶

✨ SYNOPSIS ✨

the whole signature, copy it exactly:

void parport_ip32_data_reverse (struct parport *p );

🎀 ARGUMENTS 🎀

• p — a pointer to struct parport. that’s the whole argument, no cap 💅

🦋 DESCRIPTION 🦋

okay so the actual move: place the data bus in a high impedance state, if p->modes has the PARPORT_MODE_TRISTATE bit set. that conditional is the main character here — it’s literally the vibe check for whether this high-impedance moment happens, periodt 🔥
