    Hello Prabhu,

    The most straight forward solution is to use the built in Comparator_A. Detailed use of Comparator_A can be found in chapter 16 of the Family's Users guide: www.ti.com/.../slau049

    You can use a built in voltage threshold or provide one externally. The comparator can trigger an interrupt or timer when the threshold is crossed, and this could be measured.

    Thanks,
    JD
