反汇编

  • 安装dis51
  • packihx DSLogic.ihx > DSLogic.hex
  • 反汇编：
    • cat DSLogic.hex | dis51 > DSLogic.a51
    • cat DSLogic.hex | dis51 0x80 0x00 > DSLogic.a51
      • CSEG：code segment
      • LJMP：The LJMP instruction transfers program execution to the specified 16-bit address.
      • DB：The DB statement initializes memory with one or more byte values. label is a symbol that is assigned the current memory address. expression is a byte value that is stored in memory. Each expression may be a symbol, a string, or an expression.
