You need to specify the values of M flag and X flag at the staring
address of mnemonic memory display. When the inverse-assembler
encounters an instruction which changes M flag and/or X flag (SEM,
CLM, SEP X, etc..), the value set by the instruction is used to continue
disassembling memory contents.
Note
When you use <PGUP> or <PREV> key to see the previous lines of
memory display, disassembled mnemonic may not be accurate.
