An interrupt enable bit must be set in the MMC_IE register to enable the module internal source of interrupt.
When an interrupt event occurs, the single interrupt line is asserted and the LH must:
In the MMC_STAT register, Card Interrupt (CIRQ) and Error Interrupt (ERRI) bits cannot be cleared.
The MMC_STAT[8] CIRQ status bit must be masked by disabling the MMC_IE[8] CIRQ_ENABLE bit (cleared to 0), then the interrupt routine must clear SDIO interrupt source in SDIO card common control register (CCCR).
The MMC_STAT[15] ERRI bit is automatically cleared when all status bits in MMC_STAT[31:16] are cleared.
