- :c:macro:`SDMMC_HOST_SLOT_1` is routed via GPIO Matrix. This means that any GPIO may be used for each of the SD card signals. It is for non UHS-I usage.
- :c:macro:`SDMMC_HOST_SLOT_0` is dedicated to UHS-I mode, which is not yet supported in the driver.
- :c:macro:`SDMMC_HOST_SLOT_0` is dedicated to UHS-I mode.
On {IDF_TARGET_NAME}, SDMMC host requires an external power supply for the IO voltage. Please refer to :ref:`pwr-ctrl` for details.
