General • Re: RP2040: multiple (6) GPIO interrupts

Well, there's actually a register (GPIO_OE) with one bit per pin, '1' for output, '0' for input,

So we are agreed, the text I cited is incorrect, clearing output enable does not set it for input. It is necessary but not sufficient.

Er, no we do not agree!

All pins are available for input all the time (even when muxed to other functions).

There is just one bit for the GPIO OE, but there are multiple ways of setting/clearing it. Unless you are talking about the possiblilty of the bit being muxed to a non-GPIO function (which has its own OE if applicable, or may be hard-wired).
