ADE7758 instantaneous active power

Hi I'm designing a metter with the ADE7758. I want to show Vrms, Irms, instantaneous active power ( Vrms*Irms*cos(fi) ) and energy consumption of each phase. Reading the datasheet I found that there isn't a register to read the instantaneous power, you can only read the accumulated active power which correspond to the energy.

 

It's there any way I can calculate the instant active power of each phase?
