🎀 SYNOPSIS 🎀

unsigned int ucb1x00_io_read (struct ucb1x00 *ucb );

🔥 DESCRIPTION 🔥

It returns a bitfield describing the logic state of the ten general purpose IO pins. Ten pins, one bitfield, iconic behavior fr fr.

ucb1x00_enable must have been called to enable the comms before using this function. That’s a must, not a maybe, so don’t skip it 💀

This function does not take any mutexes or spinlocks. Not a single one. The page says so, so we’re saying so. 🙈
