ADE7858A Gets Stucks


We have used ADE7858A in our product for energy measurement purpose. In few devices on field we have observed that all the electrical parameter value gets stuck and frequency value becomes 409.6 Hz. After some diagnostics we have found that RSTDONE bit in STATUS1 gets set. In this condition if we initialize all configuration register and start DSP again then it works normally for sometime then same behaviour is observed. But we are not executing soft reset or hard reset from microcontroller. ADE7858A reset pin is directly connected to microcontroller GPIO.

Is it possible that some noise on ADE7858A reset pin is causing problem? If yes then why problem is observed only on few devices? And how can I solve this issue?
