Raw Interrupt Status Register
| CDET | Card detect. Writes to bits clear status bit. Value of 1 clears status bit, and value of 0 leaves bit intact. Bits are logged regardless of interrupt mask status. |
| RE | Response error. Writes to bits clear status bit. Value of 1 clears status bit, and value of 0 leaves bit intact. Bits are logged regardless of interrupt mask status. |
| CDONE | Command done. Writes to bits clear status bit. Value of 1 clears status bit, and value of 0 leaves bit intact. Bits are logged regardless of interrupt mask status. |
| DTO | Data transfer over. Writes to bits clear status bit. Value of 1 clears status bit, and value of 0 leaves bit intact. Bits are logged regardless of interrupt mask status. |
| TXDR | Transmit FIFO data request. Writes to bits clear status bit. Value of 1 clears status bit, and value of 0 leaves bit intact. Bits are logged regardless of interrupt mask status. |
| RXDR | Receive FIFO data request. Writes to bits clear status bit. Value of 1 clears status bit, and value of 0 leaves bit intact. Bits are logged regardless of interrupt mask status. |
| RCRC | Response CRC error. Writes to bits clear status bit. Value of 1 clears status bit, and value of 0 leaves bit intact. Bits are logged regardless of interrupt mask status. |
| DCRC | Data CRC error. Writes to bits clear status bit. Value of 1 clears status bit, and value of 0 leaves bit intact. Bits are logged regardless of interrupt mask status. |
| RTO_BAR | Response time-out (RTO)/Boot Ack Received (BAR). Writes to bits clear status bit. Value of 1 clears status bit, and value of 0 leaves bit intact. Bits are logged regardless of interrupt mask status. |
| DRTO_BDS | Data read time-out (DRTO)/Boot Data Start (BDS). Writes to bits clear status bit. Value of 1 clears status bit, and value of 0 leaves bit intact. Bits are logged regardless of interrupt mask status. |
| HTO | Data starvation-by-host time-out (HTO). Writes to bits clear status bit. Value of 1 clears status bit, and value of 0 leaves bit intact. Bits are logged regardless of interrupt mask status./Volt_switch_int |
| FRUN | FIFO underrun/overrun error. Writes to bits clear status bit. Value of 1 clears status bit, and value of 0 leaves bit intact. Bits are logged regardless of interrupt mask status. |
| HLE | Hardware locked write error. Writes to bits clear status bit. Value of 1 clears status bit, and value of 0 leaves bit intact. Bits are logged regardless of interrupt mask status. |
| SBE | Start-bit error. Writes to bits clear status bit. Value of 1 clears status bit, and value of 0 leaves bit intact. Bits are logged regardless of interrupt mask status. |
| ACD | Auto command done. Writes to bits clear status bit. Value of 1 clears status bit, and value of 0 leaves bit intact. Bits are logged regardless of interrupt mask status. |
| EBE | End-bit error (read)/write no CRC. Writes to bits clear status bit. Value of 1 clears status bit, and value of 0 leaves bit intact. Bits are logged regardless of interrupt mask status. |
| SDIO_INTERRUPT | Interrupt from SDIO card. Writes to these bits clear them. Value of 1 clears bit and 0 leaves bit intact. 0 - No SDIO interrupt from card 1 - SDIO interrupt from card In MMC-Ver3.3-only mode, bits always 0. Bits are logged regardless of interrupt-mask status. |
| RESERVED | Reserved. |
