ADC of ADSP-CM408F Understanding

Hello,

I am using ADSP-CM408F internal ADC and using demo examples of ADCC_Circular given by AD. I am using all the newer versions of IAR and trying to get the digital value by running the demo code. Once I load the program into the internal Flash and execute it using IAR , the code runs for a second and then stops on its own , any idea how can i run it continuously?

Moreover, the data which is being generated in the .dat file, contains the numbers in the formal which is shown below.

It contains a lot of 0s in between which are either 4 / 5 and comes again and again. Can you explain me the reason behind this?

-> Can you also explain how these data appear? for ex. 4521 number, from which computation method did it come from?

Thanks
