ENERGY MEASUREMENT INTERNAL REGISTERS DETAILS

Table 32. Mode 1 Register (MODE1, 0x0B)

Bit

Mnemonic

Default

Description

SWRST

Setting this bit resets all of the energy measurement registers to their default values.

DISZXLPF

Setting this bit disables the zero-crossing low-pass filter.

INTE

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

SWAPBITS

Setting this bit swaps CH1 ADC and CH2 ADC.

PWRDN

Setting this bit powers down voltage and current ADCs.

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.

Table 33. Mode 2 Register (MODE2, 0x0C)

Bit

Mnemonic

Default

Description

7 to 6

CF2SEL[1:0]

Configuration bits for CF2 output.

CF2SEL[1:0]

Result

CF2 frequency is proportional to active power.

CF2 frequency is proportional to reactive power.1

CF2 frequency is proportional to apparent power or Irms.

5 to 4

CF1SEL[1:0]

Configuration bits for CF1 output.

CF1SEL[1:0]

Result

CF1 frequency is proportional to active power.

CF1 frequency is proportional to reactive power.1

CF1 frequency is proportional to apparent power or Irms.

VARMSCFCON

Configuration bits for apparent power or Irms for CF1, CF2 outputs, and VA accumulation registers

(VAHR, RVAHR, and LVAHR). Note that CF1 cannot be proportional to VA if CF2 is proportional to

Irms and vice versa.

VARMSCFCON

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 Irms.

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

ZXRMS

Logic 1 enables update of rms values synchronously to Voltage ZX.
