The protocol layer works with the host via the :cpp:class:`sdmmc_host_t` structure. This structure contains pointers to various functions of the host.
Pin Configurations
------------------
..only:: SOC_SDMMC_USE_IOMUX and not SOC_SDMMC_USE_GPIO_MATRIX
SDMMC pins are dedicated, you don't have to configure the pins.
..only:: SOC_SDMMC_USE_GPIO_MATRIX and not SOC_SDMMC_USE_IOMUX
SDMMC pin signals are routed via GPIO Matrix, so you will need to configure the pins in :cpp:type:`sdmmc_slot_config_t`.
..only:: esp32p4
SDMMC have two slots:
.. list::
- slot 0 pins are dedicated for UHS-I mode. This is not yet supported in the driver.
- slot 1 pins are routed via GPIO Matrix, and it's for non UHS-I usage. You will need to configure the pins in :cpp:type:`sdmmc_slot_config_t` to use the slot 1.
