20.6.18 Raw Interrupt Status Register (RINTSTS)
9
DRTO
Data read time-out. Interrupt enabled only if corresponding
bit in interrupt mask register is set.
0
10
HTO
Data starvation-by-host time-out (HTO). Interrupt enabled
only if corresponding bit in interrupt mask register is set.
0
11
FRUN
FIFO underrun/overrun error. Interrupt enabled only if
corresponding bit in interrupt mask register is set.
0
12
HLE
Hardware locked write error. Interrupt enabled only if
corresponding bit in interrupt mask register is set.
0
13
SBE
Start-bit error. Interrupt enabled only if corresponding bit in
interrupt mask register is set.
0
14
ACD
Auto command done. Interrupt enabled only if
corresponding bit in interrupt mask register is set.
0
15
EBE
End-bit error (read)/write no CRC. Interrupt enabled only if
corresponding bit in interrupt mask register is set.
0
16
SDIO_
INTERRUPT
Interrupt from SDIO card. SDIO interrupt for card enabled
only if corresponding sdio_int_mask bit is set in Interrupt
mask register (mask bit 1 enables interrupt; 0 masks
interrupt).
0 - No SDIO interrupt from card
1 - SDIO interrupt from card
In MMC-Ver3.3-only mode, this bit is always 0.

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.
0
1
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.
0
2
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.
0

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.
0
4
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.
0
5
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.
