Yes. Did you notice where I wrote ”fast enough to toggle a CAN transceiver”. The point is the PIO may be great at wiggling pins, but that doesn’t mean you can

Yes. Did you notice where I wrote ”fast enough to toggle a CAN transceiver”. The point is the PIO may be great at wiggling pins, but that doesn’t mean you can “support hardware protocols” you don’t have peripherals for. It means it gets you a pin wiggler, and the rest of the protocol would have to be software.
