4.5.12 Busy time out error interrupt
+ Interrupt Assert Condition
If a busy declaration from the card (DAT0 = "0" after response end) remains longer than the specified time, this
condition is considered as a time out error and 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 NRCS bit(D20) 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 NRCS bit(D20) of SD Error Detail Status Register(Offset:12C-12Fh) are set to "1".
