2, according to the data on the order read block of data block.Whether the piece of judging current selected data block number is largest block number, if greater than largest block number, shows the data read on all data blocks is finished, if smaller or equal to largest block number, then reads the data on the current data block.
3, during the data on reading current data block, once read the data of a packet with the form of packet, packet is a regular length, comprises 255 byte datas at most.The start offset address of current data block is begun reading of data as initial address, each all is the data that read a packet, if the data length on data block is the integral multiple of data packet length, the data on this data block can all be read so; If the data length on data block is not the integral multiple of data packet length, the data that can be left a data packet length of curtailment so can not be read.If length of data package is fixed as 250 bytes, have the data of 5000 bytes on the current data block, after reading 20 packets, just in time the data read on this data block can be finished so, continue to read the data of next data block.If but have the data of 5050 bytes on the data block, the data of also being left 50 bytes so after reading 20 packets are not read, the start address of instructing C to begin reading of data so is set to the start address of data left, Lc is made as the length of data left, utilizes instruction C to read the remaining data of this data block.
503, store the data that read, the data and the initialize routine that are read are merged into just pre-file;
With the data storage that read out in the disk of host computer.The data that store initialize routine and obtain from the master card nonvolatile memory in the disk of host computer will be called pre-personal data from the data that the master card nonvolatile memory obtains.Initialize routine and pre-personal data are middle with mark＜WriteUser Data〉separate.
Earlier initialize routine is write in the first pre-file of object card, afterwards pre-personal data is divided into the i piece, every is divided into j bar length is the data of Len, and length of storage is Len in the internal memory of host computer simultaneously, and content is FFF entirely ... correlation data.Then the i in the pre-personal data * j bar data and correlation data are contrasted one by one, ((n＜j) data of bar are consistent with correlation data for the piece n of m＜i) until finding m, then with the rejection of data after the m piece n bar, data before preserving, and will before all data to be reclassified as length be APDULen, the data of k section are organized as according to logical address and write the instruction of card and save as pre-individualized program altogether.Wherein, APDULen is different values with Len.If in the k segment data, there are invalid data " FF " in the data head of some section, tail, so these invalid datas are all removed, and pre-individualized program behind the removal invalid data are write the first pre-file of object card.
504, by the data address write operation described just pre-file is write object card.
At first can be by the data block on the instruction one select target card nonvolatile memory, instruction one:
| ?CLA | INS | P1 | P2 | 01 | BlockNo |
Wherein, CLA INS is the description to instruction, the data block number of BlockNo for selecting, and 01 is the shared byte length of selected data block number.
Afterwards by instructing two on selected data block, just pre-file to be write described data block by offset address.
Instruction two: press the offset address write data
| ?CLA | INS | P1 | P2 | Lc | Data |
Wherein, CLA INS is that P1P2 is the skew with respect to selected data piece start address to the description of instruction, and Data is for wanting the data of writing data blocks, and Lc is the shared byte length of Data.
So just pre-file is write in the data block of object card, just finished writing of object card software systems.
