Hi hmani,
I configured the ADE7880 that an interrupt is generated when FNLOAD or VANLOAD in the STATUS1 register is set. Then I check the PHNOLOAD (NLPHASE[x] and VANLPHASE[x]) register for all phases. If one of these bits is in no-load status, the phase of my system is in no-load. If both bits are zero, the phase is out of no-load.
I take it that energy counters of one phase stopps counting automatically if one of theese bits is in no-load!

Heimo
