+ 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".
+De-asserting Method
SD memory Card
(1) "0" is written into the SDTO bit(D3) of SD Buffer Control & Error Status Register(Offset:01E-01Fh).
(2) "1" is written into the MDTO bit(D19) of SD Interrupt Mask Register(Offset:020-023h).
(3) Hardware reset by #PCLR = “0”.
(4) Software reset by writing "0" into the SRST bit(D0) of SD Software Reset Register(Offset:0E0h).
SDIO Card
(1) "0" is written into the SDTO bit(D3) of SD Buffer Control & Error Status Register(Offset:11E-11Fh).
(2) "1" is written into the MDTO bit(D19) of SD Interrupt Mask Register(Offset:120-123h).
(3) Hardware reset by #PCLR = “0”.
(4) Software reset by writing "0" into the SRST bit(D0) of SD Software Reset Register(Offset:1E0h).
