MDD_SDSPI_SectorWrite Function

BYTE MDD_SDSPI_SectorWrite(
    DWORD sector_addr, 
    BYTE* buffer, 
    BYTE allowWriteToZero
);

The MDD_SDSPI_SectorWrite function writes 512 bytes of data from the location pointed to by 'buffer' to the specified sector of the SD card.

The MDD_SectorWrite function pointer must be pointing to this function.

None.

The card expects the address field in the command packet to be a byte address. The sector_addr value is ocnverted to a byte address by shifting it left nine times (multiplying by 512).
