 SD SPI driver is represented using an ``sdmmc_host_t`` structure initialized using ``SDSPI_HOST_DEFAULT`` macro. For slot initialization, ``SDSPI_SLOT_CONFIG_DEFAULT`` can be used to fill in default pin mapping, which is the same as the pin mapping in SD mode.
 
-SD SPI driver APIs are very similar to SDMMC host APIs. As with the SDMMC host driver, only ``sdspi_host_init``, ``sdspi_host_init_slot``, and ``sdspi_host_deinit`` functions are normally used by the applications. Other functions are called by the protocol level driver via function pointers in ``sdmmc_host_t` structure.
