44 / 152 page  ADE7116/ADE7156/ADE7166/ADE7169/ADE7566/ADE7569 Rev. B | Page 44 of 152 Address MADDPT[6:0] Mnemonic R/W Length (Bits) Signed/ Unsigned Default Description 0x25 VARDIV R/W 8 U 0 Sets var energy scaling register. 0x26 VADIV R/W 8 U 0 Sets VA energy scaling register. 0x27 CF1NUM R/W 16 U 0 Sets CF1 numerator register. 0x28 CF1DEN R/W 16 U 0x003F Sets CF1 denominator register. 0x29 CF2NUM R/W 16 U 0 Sets CF2 numerator register. 0x2A CF2DEN R/W 16 U 0x003F Sets CF2 denominator register. 0x3B Reserved 0 This register must be set to its default value for proper operation. 0x3C Reserved 0x0300 This register must be set to its default value for proper operation. 0x3D CALMODE2 R/W 8 U 0 Set calibration mode. 0x3E Reserved 0 This register must be set to its default value for proper operation. 0x3F Reserved 0 This register must be set to its default value for proper operation. 1 This function is not available in the ADE7116, ADE7156, ADE7166, or ADE7566. 2 This function is not available in the ADE7566 or ADE7569. ENERGY MEASUREMENT INTERNAL REGISTER DETAILS Table 33. MODE1 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. MODE2 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 CF2 frequency is proportional to apparent power or Irms. [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 CF1 frequency is proportional to apparent power or Irms. 3 VARMSCFCON 0 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 0 If CF1SEL[1:0] = 1X, CF1 is proportional to VA. If CF2SEL[1:0] = 1X, CF2 is proportional to VA. 1 If CF1SEL[1:0] = 1X, CF1 is proportional to Irms. If CF2SEL[1:0] = 1X, CF2 is proportional to Irms. 2 ZXRMS 0 Logic 1 enables update of rms values synchronously to Voltage ZX. |
