Expand description

Block until an SDIO interrupt is received

Slave uses D1 line to signal interrupt condition to the host. This function can be used to wait for the interrupt.

@param card pointer to card information structure previously initialized using sdmmc_card_init @param timeout_ticks time to wait for the interrupt, in RTOS ticks @return - ESP_OK if the interrupt is received - ESP_ERR_NOT_SUPPORTED if the host controller does not support IO interrupts - ESP_ERR_TIMEOUT if the interrupt does not happen in timeout_ticks
