TOSHIBA CONFIDENTIAL
(1) "0" is written into the SCRC bit(D1) of SD Buffer Control & Error Status Register(Offset:01E-01Fh).
(2) "1" is written into the MCRC bit(D17) 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).
(1) "0" is written into the SCRC bit(D1) of SD Buffer Control & Error Status Register(Offset:11E-11Fh).
(2) "1" is written into the MCRC bit(D17) 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).
If the CRC value for the response, read data or CRC status received from the card does not agree with the value
internally calculated by TC6387XB, an interrupt is generated
In the case of SD memory Card, the SCRC bit(D1) of SD Buffer Control & Error Status Register(Offset:01E-
01Fh) and the WCRCE bit, RCRCE bit, SCRCE bit and CCRCE bit(D11-8) of SD Error Detail Status
Register(Offset:02C-02Fh) are set to "1".
In the case of SDIO Card, the SCRC bit(D1) of SD Buffer Control & Error Status Register(Offset:11E-11Fh) and
the WCRCE bit, RCRCE bit and CCRCE bit(D11-10,8) of SD Error Detail Status Register(Offset:12C-12Fh) are
set to "1".
