ENERGY MEASUREMENT INTERNAL REGISTERS DETAILS
Table 33. Mode 1 Register (MODE1, Address 0x0B)
Bit Mnemonic Default Description
7
SWRST
0
Setting this bit resets all of the energy measurement registers to their default values.
6 DISZXLPF 0 Setting this bit disables the zero-crossing low-pass filter.
5 INTE 0 Setting this bit enables the digital integrator for use with a di/dt sensor.
4 SWAPBITS 0 Setting this bit swaps CH1 ADC and CH2 ADC.
3 PWRDN 0 Setting this bit powers down voltage and current ADCs.
2 DISCF2 1 Setting this bit disables Frequency Output CF2.
1 DISCF1 1 Setting this bit disables Frequency Output CF1.
0 DISHPF 0 Setting this bit disables the HPFs in voltage and current channels.
Table 34. Mode 2 Register (MODE2, Address 0x0C)
Bit Mnemonic Default Description
[7:6] CF2SEL 01 Configuration bits for CF2 output.
CF2SEL Result
00 CF2 frequency is proportional to active power
01 CF2 frequency is proportional to reactive power
1
1X
2
CF2 frequency is proportional to apparent power or I
rms
[5:4]
CF1SEL
00
Configuration bits for CF1 output.
CF1SEL Result
00 CF1 frequency is proportional to active power
01 CF1 frequency is proportional to reactive power
1
1X
2
CF1 frequency is proportional to apparent power or I
rms
3 VARMSCFCON 0 Configuration bit for apparent power or I
rms
for CF1 and CF2 outputs and VA accumulation registers (VAHR,
RVAHR, and LVAHR). Note that CF1 cannot be proportional to VA if CF2 is proportional to I
rms
, and vice versa.
VARMSCFCON Result
0 If CF1SEL = 1X, CF1 is proportional to VA
If CF2SEL = 1X, CF2 is proportional to VA
1 If CF1SEL = 1X, CF1 is proportional to I
rms
If CF2SEL = 1X, CF2 is proportional to I
rms
2 ZXRMS 0 Logic 1 enables update of rms values synchronously to Voltage ZX.
1 FREQSEL 0 Configuration bit to select period or frequency measurement for the PER_FREQ register (Address 0x0A).
FREQSEL Result
0 The PER_FREQ register holds a period measurement
1 The PER_FREQ register holds a frequency measurement
0 WAVEN 0 When this bit is set, waveform sampling mode is enabled.
