Read wait request signal transmits to SD card. The request signal
is stopped and this flag is cleared by setting one to this bit.(for
SDIO)
0 = not occur,
SDIO interrupt detects. This flag is cleared by setting one to this
bit.(for SDIO)
0 = not detect,
FIFO fail error when FIFO occurs overrun / underrun / misaligned
data saving. This flag is cleared by setting one to this bit.
0 = not detect,
CRC Status error when data block sent (CRC check failed -
returned from card). This flag is cleared by setting one to this bit.
0 = not detect,
Data block received error (CRC check failed - calculated by host).
This flag is cleared by setting one to this bit.
0 = not detect,
Data / Busy receive timeout. This flag is cleared by setting one to
this bit.
0 = not detect,
Data transfer completes (data counter is zero). This flag is cleared
by setting one to this bit.
0 = not detect,
Only busy check finish. This flag is cleared by setting one to this
bit.
0 = not detect,
Data transmit in progress.
0 = not active,
Data receive in progress.
0 = not active,
