The Atmel WILC1000 SDIO is a full speed interface. 185625f965SAjay Singh It meets SDIO card specification version 2.0. The interface supports 195625f965SAjay Singh the 1-bit/4-bit SD transfer mode at the clock range of 0-50 MHz. 205625f965SAjay Singh The host can use this interface to read and write from any register 215625f965SAjay Singh within the chip as well as configure the WILC1000 for data DMA. 225625f965SAjay Singh To use this interface, pin9 (SDIO_SPI_CFG) must be grounded.

The Atmel WILC1000 has a Serial Peripheral 345625f965SAjay Singh Interface (SPI) that operates as a SPI slave. This SPI interface can 355625f965SAjay Singh be used for control and for serial I/O of 802.11 data. The SPI is a 365625f965SAjay Singh full-duplex slave synchronous serial interface that is available 375625f965SAjay Singh immediately following reset when pin 9 (SDIO_SPI_CFG) is tied to 385625f965SAjay Singh VDDIO.
