HI TEAM, 

I am Bhairav, i am using mspm0g3507 mcu and trying to getting the interrupt in nano seconds by using the frequency of 32 mega hz internal frequency,  and checking by connecting the oscilloscope, but interrupting not getting generated for setted time.

    What timer period are you trying to achieve? How are you measuring the result?

    You should probably budget 50-60 CPU cycles (minimum) for your ISR, which would give you a minimum period of about 2 microseconds.

    Some timed activities can be done without interrupts, e.g. PWM, ADC triggering.

    Hi Ankush,

    Aggree with Bruce, we usually not implement nano seconds level interrupt, we can use hardware trigger method if it helps.

    MSPM0 provide the EVENT system to use one peripheral to trigger another peripheral, or use DMA triggerred by perpheral to transmit data.
