Field Documentation

lowVoltageSignaling

bool sdio_sd_card_config_t::lowVoltageSignaling

If true, the host supports 1.8V signaling for UHS-I cards.

busWidth

sdio_bus_width_en sdio_sd_card_config_t::busWidth

The desired bus width for data transfer

cardType

sdio_card_type_en* sdio_sd_card_config_t::cardType

Pointer to store the detected card type (SD, SDIO, Combo, or Unusable).

rca

uint32_t* sdio_sd_card_config_t::rca

Pointer to where the Relative Card Address (RCA) of the card will be stored.

cardCapacity

sdio_card_capacity_en* sdio_sd_card_config_t::cardCapacity

Stores the card capacity type (SDSC, SDHC, SDXC, or Unsupported).

clockSpeed

uint32_t sdio_sd_card_config_t::clockSpeed

Configures the SDIO clock speed in Hz.

busSpeed

uint32_t sdio_sd_card_config_t::busSpeed

Configures the bus speed mode (e.g., Default, High Speed, SDR50).
