Access ADC registers on M3 with accurate time information

Hello

I wanted to know how to accurately measure the current ADC data on M3 core of Concerto. 

I did see the post https://e2e.ti.com/support/microcontrollers/c2000/f/171/t/172476 

However, i wanted to synchronize my ADC read with the End of Conversion in the m3 core. 

Although i could have done this with interrupts on C28x, i can not find a way to do this on the Cortex M3. Could you kindly suggest.

    Hello,

    It looks like interrupts 88 through 95 on the NVIC are supposed to be for the ADC, and section 11.3.7 of the TRM says, "The ADC contains eight interrupts that can be flagged and/or passed on to the PIE and NVIC." So there must be a way to have an interrupt on the M3 tell you when the result is ready to be read. Have you tried that?

    Thanks,
    Whitney
