After Boot Sequence, Muxing

I see that the default SPI pins are used to boot from the internal flash. Is it possible to mux these pins to a different purpose such as GPIO after the boot sequence has occurred? Could this cause any issues after power down and reboot, as I believe I saw in the DS that pins revert to their last state?

Thanks,
Andy

Hi areilly,

Hi areilly,

After the booting sequence has completed the pins can be used as you like. When the system resets the pins are going to their default state and it is going to use the same pins in order to boot. When the system is waking up from sleep the GPIO's retain their state.
