set for Default speed mode or High speed mode.SDIO 1-bit Default speed mode is selected at Power On Reset.The host can change mode by sending the corresponding command over the SDIO-interface.The Default mode is showed in Figure 5-1 and Table 5-1.For the high speed mode see Figure 5-2 and Table 5-2.Condition:VDDIO_SDIO=1.7 3.6 V,Tamb=-20 +70C Figure 5-1.SDIO/SPI timing diagram(default
