The I/O buffers for each pin connected to the boot device are configured the same. See the MIO Boot Interface Pin Buffer Settings section.
Interface Connection Diagrams
The SD flash interface connections are shown in the SD Flash Interfaces section.
The SD flash interface signals are listed in the SD Flash Interface Signals section of the SD_eMMC flash memory controller chapter.
The SD_DETECT, SD_WP, and SD_BUSPWR are optional interface signals that are not required for primary boot. If the SD_DETECT and SD_WP signals are used, connecting them to the voltage level translator can provide ESD protection and pull-ups.
