Low ripple registers always read as zero.

I have been trying to find a way of "enabling" the low ripple current and voltage registers in ADE78xxA, but I don't see anything related in the datasheet, so I assume they should always be "enabled", i.e. the RMS values should always be averaged and present in those registers. Unfortunately, I only see constant zeros in all of the *_LRIP registers.


Is there any explanation for this behaviour please? I cannot read the other RMS registers quickly enough (using Raspberry PI with dev board now) nor can I use interrupts to synchronise with zero-crossing. I am using command line script at the moment.


Thank you for your help.


Kind regards,
