General • Re: RP2350 E9 bug - also for other GPIOs, e.g. SPI?

I did see a report somewhere that they had a system that left the MISO floating for some of the higher-order bits of the byte and hadn't bothered to mask off the unused bits;

I'm struggling to see this. SPI is a solidly driven bus - there are no pullups or pulldowns. If you want to multiplex slaves then they 3-state themselves until commanded by the master, which never 3-states itself.
