4.5.14 CRC status time out error interrupt
+ Interrupt Assert Condition
If the start bit of CRC status is not detected within the specified period after the end bit of block data for a write
command, an interrupt is generated. In the case of SD memory Card, the specified period is set in RTO[3:0] of SD
Memory Card Option Setup Register(Offset:028h) in the form of a multiple number of the SDCLK period. In the
case of SDIO Card, the specified period is set in TO[3:0] of SD Memory Card Option Setup Register(Offset:128h)
in the form of a multiple number of the CLK32 period.
<In the case of SD memory card>
<In the case of SDIO card>
+ Factor Evaluation Method
In the case of SD memory Card, the SDTO bit(D3) of SD Buffer Control & Error Status Register(Offset:01E-
01Fh) and the NWCS bit(D21) of SD Error Detail Status Register(Offset:02C-02Fh) are set to "1".
In the case of SDIO Card, the SDTO bit(D3) of SD Buffer Control & Error Status Register(Offset:11E-11Fh) and
the NWCS bit(D21) of SD Error Detail Status Register(Offset:12C-12Fh) are set to "1".
