Does the HAE result included VTHD and ITHD?

Hello,

 

1. Does the CM40x HAE result included VTHD and ITHD as the ADE7880?

 

2. Is there has any way to read the fundamental frequency from HAE? As described in the hardware reference manual:

"The fundamental frequency of the system is extracted from the voltage signal using the phase-locked loop

and clock control (PLL) techniques."  so I'm thinking if the frequency can read out, and it is really valuable for some application. for instance: FFT calculation.
