SD Register in SDBUS driver

MS SDBUS driver 的 SD Card Register Structure:

typedef struct _SDCARD_CARD_REGISTERS {
    union {
        UCHAR   OCR[SD_OCR_REGISTER_SIZE];          // SD OCR
        UCHAR   IO_OCR[SD_IO_OCR_REGISTER_SIZE];    // IO OCR
    };
    UCHAR   CID[SD_CID_REGISTER_SIZE];          // CID
    UCHAR   CSD[SD_CSD_REGISTER_SIZE];          // CSD
    UCHAR   SCR[SD_SCR_REGISTER_SIZE];          // SCR
}SDCARD_CARD_REGISTERS, *PSDCARD_CARD_REGISTERS;

在 \\WINCE500\PUBLIC\COMMON\OAK\DRIVERS\SDCARD\SDBUS\sddevice.hpp

這個variable 宣告在 CSDDevice 中：

    SDCARD_CARD_REGISTERS   m_CachedRegisters;      // cached registers
