  • Page 93: Mx Command

    Command Syntax Summary The 7750/51 Series microprocessors have M flag and X flag which determine data length and index register length. The inverse assembler of emulator needs to know the value of these flags to disassemble the memory contents. The mx command tells the emulator the value of M flag and/or X flag.
