    Hi Raj,

    If I understand you correctly, what you are looking for is the cycle count between start of ISR1 and start of ISR2. Is that right?

    Have you looked at the ERAD module? It includes a set of bus comparators and counters. In your case, you can configure 2 bus comparators to detect the events PC=start of ISR1 and PC=start of ISR2 and run counter using these events as start and stop events. For more details, you can refer to the appnote https://www.ti.com/lit/an/spracm7/spracm7.pdf

    You can also check the examples in C2000ware driverlib.

    Alternatively,  you can also use the CPU timers as background counter.

    Regards,

    Veena
