For those knocking RPi for a few faults on this chip, maybe they'd like to look how a huge multi-national like STMicroelectronics does it :

71 pages of errata covering problems all over the chip !!!
It takes ages to go through them all to work out if they affect you and what workarounds you need. Some things are marked as simply 'does not work' - end of story.
It's impossible to design a perfect logic chip and it's the job of any design engineer to work around this problems. TBH errata 9 is easy to overcome - just add a CMOS buffer IC. Compared with the RP2040 which needed an STM32G series on the side for commercial applications, this chip is still a huge improvement and I think people should be congratulating them, not slagging them off and demanding a hugely expensive respin that no other MCU supplier would even consider making. STM wouldn't even respin some of the F series MCUs when their security system was blown wide open by some hacker, and that was far more serious.
