I'm trying to figure out if I can connect two CT sensors to measure mains current (split single phase 120v each in North America) to the atm90e26 chip:

I see by default the second channel isn't setup to use a CT, but it looks like it can be configured to do so, is that correct?

I've seen examples of 2 of this chip being used to measure each line. It looks like the ATM90E36A can definitely use 2 CT's, but it appears to be a bit overkill for a single split phase, as it can do 4 current channels 3 voltage, and is made for 3 phase measurement.
