how ADE7758 chip knows what ct i am using, assume a ct with burdern resistor of x

it produces 100mv / amp , if i reduce the burdern resistor to half of x then i will get 50mv/amp, how this information is fed to the ad7758 chip. how much mv/ amp i must give. is there any register for this. assume i am connecting 1 amps load i a phase if i read a phase rms current i must get 1 amps how to calibrate this
 

the current is read thro(as o/p of ct voltage) in current channel adc of ade7758 .
the gain of the input stage can be set for the reqd value.

Register 0x23 deals with that.
