Setting a bit clears the corresponding interrupt and writing 0 has no effect. Bits are logged regardless of interrupt mask status. Bit 15 (EBE): End-bit error/no CRC error; Bit 14 (ACD): Auto command done; Bit 13 (SBE/BCI): RX Start Bit Error; Bit 12 (HLE): Hardware locked write error; Bit 11 (FRUN): FIFO underrun/overrun error; Bit 10 (HTO): Data starvation by host timeout (HTO); Bit 9 (DTRO): Data read timeout; Bit 8 (RTO): Response timeout; Bit 7 (DCRC): Data CRC error; Bit 6 (RCRC): Response CRC error; Bit 5 (RXDR): Receive FIFO data request; Bit 4 (TXDR): Transmit FIFO data request; Bit 3 (DTO): Data transfer over; Bit 2 (CD): Command done; Bit 1 (RE): Response error; Bit 0 (CD): Card detect.

Interrupt from SDIO card, one bit for each card. Bit[17:16] correspond to card1 and card0, respectively. Setting a bit clears the corresponding interrupt bit and writing 0 has no effect. 0: No SDIO interrupt from card; 1: SDIO interrupt from card.
