Description
Setting this bit will reset all of the energy measurement registers to their
default values
Setting this bit disables the zero-crossing lowpass filter
Setting this bit enables the digital integrator for use with a di/dt sensor
Setting this bit swaps CH1 & CH2 ADCs
Setting this bit powers down voltage and current ADC’s
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
