49 / 56 page  Data Sheet ADE7763 Rev. C | Page 49 of 56 Address Name R/W No. Bits Default Type1 Description 0x11 APOS R/W 16 0x0 S Active Power Offset Correction. This 16-bit register allows small offsets in the active power calculation to be removed—see the Active Power Calculation section. 0x12 WGAIN R/W 12 0x0 S Power Gain Adjust. This is a 12-bit register. Calibrate the active power calculation by writing to this register. The calibration range is ±50% of the nominal full-scale active power. The resolution of the gain adjust is 0.0244%/LSB —see the Calibrating an Energy Meter section. 0x13 WDIV R/W 8 0x0 U Active Energy Divider Register. The internal active energy register is divided by the value of this register before being stored in the AENERGY register. 0x14 CFNUM R/W 12 0x3F U CF Frequency Divider Numerator Register. Adjust the output frequency on the CF pin by writing to this 12-bit read/write register—see the Energy-to-Frequency Conversion section. 0x15 CFDEN R/W 12 0x3F U CF Frequency Divider Denominator Register. Adjust the output frequency on the CF pin by writing to this 12-bit read/write register—see the Energy-to-Frequency Conversion section. 0x16 IRMS R 24 0x0 U Channel 1 RMS Value (Current Channel). 0x17 VRMS R 24 0x0 U Channel 2 RMS Value (Voltage Channel). 0x18 IRMSOS R/W 12 0x0 S Channel 1 RMS Offset Correction Register. Note that for correct operation only positive values should be written to the IRMSOS register. 0x19 VRMSOS R/W 12 0x0 S Channel 2 RMS Offset Correction Register. 0x1A VAGAIN R/W 12 0x0 S Apparent Gain Register. Calibrate the apparent power calculation by writing to this register. The calibration range is 50% of the nominal full- scale real power. The resolution of the gain adjust is 0.02444%/LSB. 0x1B VADIV R/W 8 0x0 U Apparent Energy Divider Register. The internal apparent energy register is divided by the value of this register before being stored in the VAENERGY register. 0x1C LINECYC R/W 16 0xFFFF U Line Cycle Energy Accumulation Mode Line-Cycle Register. This 16-bit register is used during line cycle energy accumulation mode to set the number of half line cycles for energy accumulation—see the Line Cycle Energy Accumulation Mode section. 0x1D ZXTOUT R/W 12 0xFFF U Zero-Crossing Timeout. If no zero crossings are detected on Channel 2 within the time specified in this 12-bit register, the interrupt request line (IRQ) will be activated—see the Zero-Crossing Detection section. 0x1E SAGCYC R/W 8 0xFF U Sag Line Cycle Register. This 8-bit register specifies the number of consecutive line cycles below SAGLVL that is required on Channel 2 before the SAG output is activated—see the Line Voltage Sag Detection section. 0x1F SAGLVL R/W 8 0x0 U Sag Voltage Level. An 8-bit write to this register determines at what peak signal level on Channel 2 the SAG pin becomes active. The signal must remain low for the number of cycles specified in the SAGCYC register before the SAG pin is activated—see the Line Voltage Sag Detection section. 0x20 IPKLVL R/W 8 0xFF U Channel 1 Peak Level Threshold (Current Channel). This register sets the level of current peak detection. If the Channel 1 input exceeds this level, the PKI flag in the status register is set. 0x21 VPKLVL R/W 8 0xFF U Channel 2 Peak Level Threshold (Voltage Channel). This register sets the level of voltage peak detection. If the Channel 2 input exceeds this level, the PKV flag in the status register is set. 0x22 IPEAK R 24 0x0 U Channel 1 Peak Register. The maximum input value of the current channel, since the last read of the register is stored in this register. 0x23 RSTIPEAK R 24 0x0 U Same as Channel 1 peak register, except that the register contents are reset to 0 after a read. 0x24 VPEAK R 24 0x0 U Channel 2 Peak Register. The maximum input value of the voltage channel, since the last read of the register is stored in this register. 0x25 RSTVPEAK R 24 0x0 U Same as Channel 2 peak register, except that the register contents are reset to 0 after a read. |
