ADE9078 - first ADC values -


I have a problem with the first values of the Burts read Adress : 0x607.0x61C.

I wait until the ADE set the RSTDONE bit in STATUS1 and then I configure all register and starts the chip.

When I make the first burst read I get "crazy" values for all rms-values, for example AIRMS_1 = 0x7A4F780A.

The next access of the register is 0x00000000.

To fix the problem I have to know what happens inside the ADE and is only the first value wrong ?

I tried with different delays, 1second, 3 seconds, 10 seconds, after configuration and only 10 seconds solve the problem.

Can you help me ?
