by software.How can I do it?

If you are talking about In-System Programming (ISP) then you can write a windows program to call the command line version of Flash Magic and perform any operations you want.
If you are talking about In-Application Programming (IAP) then we have a library on our web site that makes the IAP calls look like C functions. You might have to modify it slightly from the Rx2 version (check the SFR locations). Also if you are not using the Keil or Raisonance compilers then you will need to rewrite the C - Assembler interface. The actual assembler code will probably remain the same however.
