    Hi Mingi,

    Are you asking if there is a way to view something like the the highlighted waveform below? If so, you can use the DAC. You'll need to write the value of TBCTR at a periodic rate to the DACVALS 12-bit register. To write the TBCTR value at a periodic rate you can use a CPU interrupt or utilize the DMA. 

    Let me know if you have any questions.

    Best Regards,

    Marlyn
