It is intended for use by post-ROM boot stage components, via the ROM Vector Table." Once invoked the part will drop down to its BootROM USB recovery mode. Should it be the case that the part is in secure boot mode - only an appropriately signed binary will be accepted by the ROM and subsequently executed.
