      • Determining MMC Card inserted by pin SDCD is transited to low; and
      • Determining MS Card inserted by pin MSINS is transited to low.
  • FIG. 5 is a flow chart of determine execution and step analysis according to an exemplary embodiment of the present invention. Operations begin at a first block 31 to detecting the voltage level transitions of the signals transmitted from pins of a plurality of flash memory card slots. At the next block 32 to determine insertion, type and numbers of flash memory cards by the voltage level transitions of the signals. At the next block 33 to determine whether more than one kind of flash memory card are inserted. If it is, then jump to the block 34, if it is not, then jump to the block 35. At the block 34 to provide at least a warning message to users for choosing one flash memory card to use. At the block 35 to execute the corresponding flash memory card program to access the data of the flash memory card.
  • Consequently, a detecting method for determining type and insertion of flash memory card is provided, more particularly suitable for the device with multiple flash memory card slots in one flash memory card interface. The control module detects the voltage level transitions of wires connected to pins of a plurality of flash memory card slots and compares the database of corresponding transitions of pins of each flash memory card, then determines the insertion, type and numbers of flash memory cards, and then access the data. The detecting method further comprises the functions of warning users. If more than one kind of flash memory card are inserted in one time, then at least a warning message is showed to users to tell users to choose one flash memory card to use and to remove other disused flash memory card. If at least two flash memory cards are inserted, then at least a warning message is showed. If only one flash memory card is inserted, then starting to execute the corresponding flash memory card program.
  • Finally, those skilled in the art should appreciate that they can readily use the disclosed conception and specific embodiments as a basis for designing or modifying other structures for carrying out the same purposes of the present invention without departing from the spirit and scope of the invention as defined by the appended claims.
