ADE7116/ADE7156/ADE7166/ADE7169/ADE7566/ADE7569
ADE7566/ADE7569 can be synchronized to the voltage channel
zero crossing so that active energy can be accumulated over an
integral number of half-line cycles. The advantage of summing
the active energy over an integer number of line cycles is that the
sinusoidal component in the active energy is reduced to 0. This

eliminates any ripple in the energy calculation. Energy is
calculated more accurately and more quickly because the
integration period can be shortened. By using this mode, the
energy calibration can be greatly simplified, and the time
required to calibrate the meter can be significantly reduced.
In the line cycle active energy accumulation mode, the ADE7116/
ADE7156/ADE7166/ADE7169/ADE7566/ADE7569
accumulate the active power signal in the LWATTHR register
(Address 0x03) for an integral number of line cycles, as shown in
Figure 70. The number of half-line cycles is specified in the
LINCYC register.

Active Energy Pulse Output
All of the ADE7116/ADE7156/ADE7166/ADE7169/ADE7566/
ADE7569 circuitry has a pulse output whose frequency is
proportional to active power (see the Active Power Calculation
section). This pulse frequency output uses the calibrated signal
from the WGAIN register (Address 0x1D) output, and its
behavior is consistent with the setting of the active energy
accumulation mode in the ACCMODE register (Address 0x0F).
The pulse output is active low and should preferably be
connected to an LED, as shown in Figure 80.

ADE7569 can accumulate active power for up to 65,535 half-
line cycles. Because the active power is integrated on an integral
number of line cycles, the CYCEND flag (Bit 2) in the Interrupt
Status 3 SFR (MIRQSTH, Address 0xDE) is set at the end of an
active energy accumulation line cycle. If the CYCEND enable
bit (Bit 2) in the Interrupt Enable 3 SFR (MIRQENH, Address
0xDB) is set, the 8052 core has a pending ADE interrupt. The
ADE interrupt stays active until the CYCEND status bit is
cleared (see the Energy Measurement Interrupts section).
Another calibration cycle starts as soon as the CYCEND flag is
set. If the LWATTHR register (Address 0x03) is not read before a
new CYCEND flag is set, the LWATTHR register is overwritten
by a new value.
