Description
Setting this bit resets all of the energy measurement registers to their default values.
Setting this bit disables the zero-crossing low-pass filter.
Setting this bit enables the digital integrator for use with a di/dt sensor.
Setting this bit swaps CH1 ADC and CH2 ADC.
Setting this bit powers down voltage and current ADCs.
Setting this bit disables Frequency Output CF2.
Setting this bit disables Frequency Output CF1.
Setting this bit disables the HPFs in voltage and current channels.

Result
CF2 frequency is proportional to active power.
CF2 frequency is proportional to reactive power.
CF2 frequency is proportional to apparent power or I
Result
CF1 frequency is proportional to active power.
CF1 frequency is proportional to reactive power.
CF1 frequency is proportional to apparent power or I
Result
If CF1SEL[1:0] = 1X, CF1 is proportional to VA
If CF2SEL[1:0] = 1X, CF2 is proportional to VA
If CF1SEL[1:0] = 1X, CF1 is proportional to I
If CF2SEL[1:0] = 1X, CF2 is proportional to I
Result
PER_FREQ register holds a period measurement
PER_FREQ register holds a frequency measurement
