The ROM execution is directed through the main boot mode pins. This provides flexibility through additional booting peripherals. The device must be powered and functional.
Main boot mode pins are shown in Table 5-2.
Any Bootmode pins marked as Reserved or not used must be tied high or low with pull resistors. They should not be left floating.
