i.MX502 IOMUX for NOR Flash boot

I'm configuring NOR Flash as boot device by looking at Table 6-9 in RM below.



Does this instruct that,  for NOR Flash boot, the Flash pins must be connected to the Pads specified in this table?

Then ROM code configures the IOMUXes the Pads without setting correspondent GPIO pins?



Does this sentence mean that we need to the configure shadowed pins by GPIO to be assingned propery to the specified Pad at reset?



However we don't need to configure manually for non-shadowed pins because ROM code does that.

We only need to conigure shadowed pins by GPIO.

Is this correct?


Best regards,
