− | These registers are used to access the system [[Flash_Filesystem|NAND]] and the inserted SD card. Both devices use the same interface. Despite the bus clock of the ARM9 beeing double of the DSi in 3DS mode the SDMMC controller has HCLK=33.513982 MHz. | + | These registers are used to access the system [[Flash_Filesystem|NAND]] and the inserted SD card.
