This bit indicate the current channel used to measure energy in anti-
tampering mode.
0 – Channel A
1 – Channel B
Configuration bit to select event that will trigger a Fault interrupt
0 – FAULT interrupt occurs when part enters Fault Mode
1 – FAULT interrupt occurs when part enters Normal Mode
Configuration bit to select event that will trigger an reactive power sign
interrupt
0 – VARSIGN interrupt occurs when reactive power changes from positive
to negative
1 - VARSIGN interrupt occurs when reactive power changes from negative
to positive
Configuration bit to select event that will trigger an active power sign
interrupt
0 – APSIGN interrupt occurs when active power changes from positive to
negative
1 - APSIGN interrupt occurs when active power changes from negative to
positive
Logic one enables absolute value accumulation of Reactive power in
energy register and pulse output
Logic one 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 and the VARCF
output.
Logic one enables positive only accumulation of Active power in energy
register and pulse output
Logic one enables absolute value accumulation of Active power in energy
register and pulse output
