Description
Waveform Register. When WSMP (Bit 3) in the interrupt enable register is
set to 1, this read-only register contains the sampled waveform data from
either Channel 1, Channel 2, or the active power signal. The data source
and the length of the waveform registers are selected by Bits 14 and 13 in
sections.
0x02
AENERGY
R

0x0
S
Active Energy Register. Active power is accumulated (integrated) over
time in this 24-bit, read-only register—see the Energy Calculation
section.
0x03
RAENERGY

S
Same as the active energy register, except that the register is reset to 0
following a read operation.

Line Accumulation Active Energy Register. The instantaneous active
power is accumulated in this read-only register over the LINECYC number
of half line cycles.

MODE
R/W

0x000C
U
Mode Register. This is a 16-bit register through which most of the
ADE7763’s functionality is accessed. Signal sample rates, filter enabling,
and calibration modes are selected by writing to this register. The
contents can be read at any time—see the Mode Register (0X09) section.
0x0A
IRQEN
R/W
16
0x40
U
Interrupt Enable Register. ADE7763 interrupts can be deactivated at any
time by setting the corresponding bit in this 16-bit enable register to
Logic 0. The status register continues to detect an interrupt event even if
disabled; however, the IRQ output is not activated—see the Interrupts
section.
0x0B
STATUS
R
16
0x0
U
Interrupt Status Register. This is a 16-bit read-only register that contains
information regarding the source of ADE7763 interrupts—see the
Interrupts section.
0x0C
RSTSTATUS
R
16
0x0
U
Same as the interrupt status register, except that the register contents are
reset to 0 (all flags cleared) after a read operation.
0x0D
CH1OS
R/W
8
0x00
S *
Channel 1 Offset Adjust. Bit 6 is not used. Writing to Bits 0 to 5 allows
offsets on Channel 1 to be removed—see the Analog Inputs and CH1OS
Register sections. Writing Logic 1 to the MSB of this register enables the
digital integrator on Channel 1; writing Logic 0 disables the integrator.
The default value of this bit is 0.
0x0E
CH2OS
R/W
8
0x0
S *
Channel 2 Offset Adjust. Bits 6 and 7 are not used. Writing to Bits 0 to 5 of
this register allows offsets on Channel 2 to be removed—see the Analog
Inputs section. Note that the CH2OS register is inverted. To apply a
positive offset, a negative number is written to this register.
0x0F
GAIN
R/W
8
0x0
U
PGA Gain Adjust. This 8-bit register is used to adjust the gain selection for
the PGA in Channels 1 and 2—see the Analog Inputs section.
0x10
PHCAL
R/W
6
0x0D
S
Phase Calibration Register. The phase relationship between Channel 1
and 2 can be adjusted by writing to this 6-bit register. The valid content
of this twos complement register is between 0x1D to 0x21. At the line
frequency of 60 Hz, this ranges from –2.06° to +0.7°—see the Phase
Compensation section.
