CHAPTER 7: DISASSEMBLER

7.5 Disassembling Output

The data/code mnemonics are restored from the target code. As for the branch instructions, a label will
be automatically generated such as "CODEx:" where "x" denotes a hexadecimal number string. Other
reference symbols will also be generated as "LABELx", "IOx" and "RAMx". The ".org" pseudo-instruction
is used to specify the starting location of each code block.
The following shows examples of disassembled sources:
