SDIO irq is not triggered by low level, but by falling edge in our previous IC. This mechanism only have one chance to catch the SDIO irq if a SDIO irq comes within the multiple block transmission. This SDIO irq may be easily lost, because falling edge appears only once within 2 clock after data transmission is completed. SDIO irq recheck mechanism will make sure all irqs can be processed correctly.
