Reading AV_WAV Register ADE9153


Im working on a project with the ADE9153A.

Everything works so far, except I´d like to read the instantaneous voltage and current values in the AV_WAV and AI_WAV registers (should be raw data, no RMS processed?).

Instantaneous voltage and current measurement should be supported according to the Reference Manual?

However when i read these registers i don´t get anything near the input voltage wave form.

How do I read these registers correctly and how can the instantaneous voltage and current be calculated from these values?
