   6          *           The main function is SD and MMC card reader.

  10          * Coments: This is the SD/MMC card reader firmware.
  11          *                  When read sector,the 512 pingpong FIFO mechanism
  12          *                  is used to improve performance.But when write sector,
  13          *                  only single FIFO is used.
  14          *

  16          *
  17          *                  The 512 pingpong FIFO mechanism is also used when 
  18          *                  writting sectors.

  23          *                  Don't set FIFO_FULL bit in SetBulkInFull() function.
  24          *                  Setting it in BulkSetDmaIn() function.
