When card insertion or removal in the slot is detected, the status will be sent to the CPU via interrupt methodology. The active low card signal SDCD_n is set to 0 during card detection. The SDMMC_PRESENT_STATE.CARD_INSERTED bit indicates whether a card has been inserted. A change from 0 to 1 generates a Card Insertion interrupt in the Normal Interrupt Status register SDMMC_INT_STATUS_NORM.CARD_INS = 1, and a change from 1 to 0 generates a Card Removal
Interrupt in the Normal Interrupt Status register SDMMC_INT_STATUS_NORM.CARD_REMOVAL = 1.
