E3MODE[1:0] in the Modes register when E1MODE is
When both E2MODE bits are high, the E1MODE bits
are enabled, allowing active, apparent, reactive, or wide
band reactive energy for both energy channels to be
output on E1 and E2. Table 6 lists the functions of E1
and E2 with E1MODE enabled.
When E1MODE bits are enabled, the E3 pin outputs ei-
ther the power fail monitor status, or the sign of the E1
and E2 outputs. Table 7 list the functions of the E3 pin
using E3MODE[1:0] in the Modes register when
E1MODE is enabled .

6.9 Energy Pulse Width
Note: Energy Pulse Width ( PulseWidth ) only applies to
E1, E2, or E3 pins that are configured to output pulses.
When any are configured to output steady-state signals,
such as voltage1 sign, power fail monitor, or energy
sign, pulse widths and output rates do not apply.
The pulse width time (t
in the PulseWidth register which is an integer multiple of
the sample or output word rate (OWR). At OWR of
4000 Hz (a period of 250 uS) t
250 uS. By default, PulseWidth is set to 1.
6.10 Energy Pulse Rate
The full-scale pulse frequency of enabled E1, E2, E3
pins is the value in PulseRate x output word rate
(OWR)/2. The actual pulse frequency is the full-scale
pulse frequency multiplied by the pulse register’s
( E
Example:
If the output word rate (OWR) is 4000 Hz, and the
PulseRate register is set to 0.05, the full-rate pulse fre-
quency is 0.05 x 4000 / 2 = 100 Hz. If the E
ter, driving E1, is 0.4567, the pulse output rate on E1 will
be 100 Hz x 0.4567 = 45.67 Hz.
6.11 Voltage Sag/Current Fault Detection
Voltage sag detection is used to determine when aver-
aged voltage falls below a predetermined level for a
specified interval of time. Current fault detection deter-
mines when averaged current falls below a predeter-
mined level for a specified interval of time.
The specified interval of time (duration) is set by the val-
ue in the V1Sag
( I2Fault

The value is in output word rate (OWR) samples. The
predetermined level is set by the values in the
