Problem with ADUC847

Hello!

After reset ADUC847 from WDT internal 24-bit sigma-delta ADC changes its own measurement results (about 10%).

When we make the same reset second time, ADC changes its own measurement results to normal (  error 10% disappears)

It depends on how many resets from internal WDT we made - even number - it's Ok -  ADC  works well, - odd number we get error.

We  have to count and recocrd on flash memory how many resets we made odd or even.

It's pretty hard work for our device )

Reference we're using external - AD780

Could you please advices how we could solve this problem?

Thank you in advance!
