Phase B Voltage Channel RMS Register.
Description
Phase C Voltage Channel RMS Register.
Frequency of the Line Input Estimated by the Zero-Crossing Processing.
It can also display the period of the line input. Bit 7 of the LCYCMODE
register determines if the reading is frequency or period. Default is
frequency. Data Bit 0 and Bit 1 of the MMODE register determine the
voltage channel used for the frequency or period calculation.
Temperature Register. This register contains the result of the latest
temperature conversion. Refer to the Temperature Measurement
section for details on how to interpret the content of this register.
Waveform Register. This register contains the digitized waveform of one
of the six analog inputs or the digitized power waveform. The source is
selected by Data Bit 0 to Bit 4 in the WAVMODE register.
Operational Mode Register. This register defines the general
configuration of the ADE7758 (see Table 18).
Measurement Mode Register. This register defines the channel used for
period and peak detection measurements (see Table 19).
Waveform Mode Register. This register defines the channel and sampling
frequency used in the waveform sampling mode (see Table 20).
Computation Mode Register. This register configures the formula
applied for the energy and line active energy measurements (see Table 22).
Line Cycle Mode Register. This register configures the line cycle
accumulation mode for WATT-HR, VAR-HR, and VA-Hr (see Table 23).
IRQ Mask Register. It determines if an interrupt event generates an
active-low output at the IRQ pin (see the
IRQ Status Register. This register contains information regarding the
source of the ADE7758 interrupts (see the
IRQ Reset Status Register. Same as the STATUS register, except that its
contents are reset to 0 (all flags cleared) after a read operation.
Zero-Cross Timeout Register. If no zero crossing is detected within the
time period specified by this register, the interrupt request line (IRQ)
goes active low for the corresponding line voltage. The maximum
timeout period is 2.3 seconds (see the
Line Cycle Register. The content of this register sets the number of
half-line cycles that the active, reactive, and apparent energies are
accumulated for in the line accumulation mode.
SAG Line Cycle Register. This register specifies the number of consecutive
half-line cycles where voltage channel input may fall below a threshold
level. This register is common to the three line voltage SAG detection.
The detection threshold is specified by the SAGLVL register (see the Line
Voltage SAG Detection section).
SAG Voltage Level. This register specifies the detection threshold for the
SAG event. This register is common to all three phases’ line voltage SAG
detections. See the description of the SAGCYC register for details.
Voltage Peak Level Interrupt Threshold Register. This register sets the
level of the voltage peak detection. Bit 5 to Bit 7 of the MMODE register
determine which phases are to be monitored. If the selected voltage
phase exceeds this level, the PKV flag in the IRQ status register is set.
Current Peak Level Interrupt Threshold Register. This register sets the
level of the current peak detection. Bit 5 to Bit 7 of the MMODE register
determine which phases are to be monitored. If the selected current
phase exceeds this level, the PKI flag in the IRQ status register is set.
Voltage Peak Register. This register contains the value of the peak
voltage waveform that has occurred within a fixed number of half-line
cycles. The number of half-line cycles is set by the LINECYC register.
