   The main reason I did it that way was to have the RMII TX start sequence generated by the PIO program, and to have a loop to output the data I'd need double the frequency of the RMII, so I had to clock it at 100MHz. So either injecting

   I could have used the 50MHz output from the PHY module and inject it into the XTAL input of the RP2040 to feed the PLL and run the MCU at a higher frequency, but it was much easier to do it the other way around by removing a resistor and mo
