CLA在线仿真的疑问

    MMOV32     MR0,@_X4                      ;1 Load MR0 with X4

    MMOV32     MR1,@_A4                      ;2 Load MR1 with A4

    MMOV32     MR3,@_B                      ;2 Load MR1 with A4

    MNOP                                     ;3 Wait till I8 to read result

    MNOP                                     ;4 Wait till I8 to read result

    MNOP                                     ;5 Wait till I8 to read result

    MNOP                                     ;6 Wait till I8 to read result

    MNOP                                     

    MUI16TOF32 MR2,  @_AdcResult.ADCRESULT1  ;8 Read ADCRESULT1 and convert to float

    MMPYF32    MR2, MR1, MR0                 

 || MMOV32     @_X0, MR2

在在线仿真的时候程序运行到MDEBUGSTOP 就暂停了，然后我可以进行单步调试，（当然此时指针是在反汇编编码中的）但是我把MR0，MR1、、、AdcResult.ADCRESULT1  等变量加到watch windown中却不能看到变量的值，我需要怎么做才可以看到单步调试变量的变化呢？从而去调试我的程序呢？谢谢
