Bit Mnemonic Default Description
[3:2] VARNOLOAD
1
00 Reactive power no load threshold.
VARNOLOAD Result
00 No load detection disabled
01 No load detection enabled with threshold = 0.015% of full scale
10 No load detection enabled with threshold = 0.0075% of full scale
11 No load detection enabled with threshold = 0.0037% of full scale
[1:0] APNOLOAD 00 Active power no load threshold.
APNOLOAD Result
00 No load detection disabled
01 No load detection enabled with threshold = 0.015% of full scale
10 No load detection enabled with threshold = 0.0075% of full scale
11 No load detection enabled with threshold = 0.0037% of full scale

Table 37. Accumulation Mode Register (ACCMODE, Address 0x0F)
Bit Mnemonic Default Description
7 ICHANNEL
1
0 This bit indicates the current channel used to measure energy in antitampering mode.
0 = Channel A (I
PA
)
1 = Channel B (I
PB
)
6 FAULTSIGN
1
0 Configuration bit to select the event that triggers a fault interrupt.
0 = FAULT interrupt occurs when part enters fault mode
1 = FAULT interrupt occurs when part enters normal mode
5 VARSIGN
2
0
Configuration bit to select the event that triggers a reactive power sign interrupt. If cleared to 0,
a VARSIGN interrupt occurs when reactive power changes from positive to negative. If set to 1, a
VARSIGN interrupt occurs when reactive power changes from negative to positive.
4 APSIGN 0
Configuration bit to select event that triggers an active power sign interrupt. If cleared to 0, an
APSIGN interrupt occurs when active power changes from positive to negative. If set to 1, an
APSIGN interrupt occurs when active power changes from negative to positive.
3 ABSVARM
2
0
Logic 1 enables absolute value accumulation of reactive power in energy register and pulse
output.
2 SAVARM
2
0
Logic 1 enables reactive power accumulation depending on the sign of the active power. If
active power is positive, var is accumulated as it is. If active power is negative, the sign of the var
is reversed for the accumulation. This accumulation mode affects both the var registers (VARHR,
RVARHR, LVARHR) and the pulse output when connected to var.
2
1 POAM 0 Logic 1 enables positive-only accumulation of active power in energy register and pulse output.
0 ABSAM 0
Logic 1 enables absolute value accumulation of active power in energy register and pulse
output.

PGA2 Result
000 Gain = 1
001 Gain = 2
010 Gain = 4
011 Gain = 8
100 Gain = 16
