To Update from ADE7816 to ADE9000

Previously I am using ADE7816 energy metering ic for the single phase energy monitoring purpose, I use 6000 line cycles as count in the LINECYC register to configure it for 1 min.

Now, I need to use ADE9000 ic for Three phase energy monitoring purpose. please suggest me Registers to be used and count value to write in the Registers for the period of 1 min.
