Card insertion. This bit is set if PRSSTAT[CINS] changes from 0 to 1. When the host driver writes 1 to this bit to clear
it, the status of PRSSTAT[CINS] should be confirmed. Because the card-detect state may be changed when the
host driver clears this bit, an interrupt event may not be generated.
When this bit is cleared, it is set again if a card has been inserted. To leave it cleared, clear IRQSTATEN[CINSEN].
0 Card state unstable or removed
1 Card inserted
Buffer read ready. This bit is set if PRSSTAT[BREN] changes from 0 to 1.
0 Not ready to read buffer
1 Ready to read buffer
Buffer write ready. This bit is set if PRSSTAT[BWEN] changes from 0 to 1.
0 Not ready to write buffer
1 Ready to write buffer
DMA interrupt. Occurs when the internal DMA finishes the data transfer successfully. If errors occur during data
transfer, this bit is not set. Instead, the DMAE bit is set.
0 No DMA interrupt
1 DMA interrupt is generated
Block gap event. If PROCTL[SABGREQ] is set, this bit is set when a read or write transaction is stopped at a block
gap. If PROCTL[SABGREQ] is cleared, this bit is not set.
During a read transaction, this bit is set at the falling edge of the SDHC_DAT line active status (when the transaction
is stopped at SD bus timing). Read wait must be supported to use this function.
During a write transaction, this bit is set at the falling edge of PRSSTAT[WTA] (after reading the CRC status at SD
bus timing).
0 No block gap event
1 Transaction stopped at block gap
Transfer complete. This bit is set when a read or write transfer is completed.
For a read transaction, this bit is set at the falling edge of PRSSTAT[WTA]. There are two cases in which this interrupt
is generated:
For a write transaction, this bit is set at the falling edge of PRSSTAT[DLA]. There are two cases in which this interrupt
is generated:
Command complete. This bit is set when the end bit of the command response is received (except Auto CMD12).
Refer to PRSSTAT[CIHB].
