Description

SWRST

Setting this bit will reset all of the energy measurement registers to their

default values

DISZXLPF

Setting this bit disables the zero-crossing lowpass filter

INTE

Setting this bit enables the digital integrator for use with a di/dt sensor

SWAPBITS

Setting this bit swaps CH1 & CH2 ADCs

PWRDN

Setting this bit powers down voltage and current ADC’s

DISCF2

Setting this bit disables Frequency output CF2

DISCF1

Setting this bit disables Frequency output CF1

DISHPF

Setting this bit disables the HPFs in voltage and current channels

Description

7-6

CF2SEL[1:0]

Configuration bits for CF2 output

CF2SEL[1:0]

Source

CF2 frequency is proportional to active power

CF2 frequency is proportional to reactive power

CF2 frequency is proportional to apparent power or

IRMS

5-4

CF1SEL[1:0]

Configuration bits for CF1 output

CF1SEL[1:0]

Source

CF1 frequency is proportional to active power

CF1 frequency is proportional to reactive power

CF1 frequency is proportional to apparent power or

IRMS

VARMSCFCON

Configuration bits for apparent power or IRMS for CF1 and CF2 outputs

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 IRMS

If CF2SEL[1:0]=1x, CF2 is proportional to IRMS

Note that CF1 cannot be proportional to VA if CF2 is proportional to IRMS

and vice versa

ZXRMS

Logic one enables update of RMS values synchronously to voltage ZX

FREQSEL

Configuration bits to select PERIOD or FREQUENCY measurement for

PER_FREQ register (0Ah)

PER_FREQ register holds a period measurement

PER_FREQ register holds a frequency measurement

Reserved

This bit should be kept to one
