The problem seems to arise when I am trying to access ADC continuously without delay. When I tried to access ADC continuously, the "Resource temporarily unavailable" error remained constant and I was not able to read ADC unless I rebooted the system.
If I give a delay after reading each ADC value, Occassionally I do get "Resource temporarily unavailable" error but it just remains for a few seconds and I am able to read ADC again normally.
