Description
Reserved.
Setting this bit enables the zero crossing output signal on P1.2.
Setting this bit enables the zero crossing output signal on P0.5.
Description
1 = a FAULTSIGN interrupt occurs when the part enters normal mode.
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.
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.
Logic 1 enables absolute value accumulation of reactive power in energy register and pulse output.
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.
Logic 1 enables positive-only accumulation of active power in energy register and pulse output.
Logic 1 enables absolute value accumulation of active power in energy register and pulse output.
This bit indicates the current channel used to measure energy in antitampering mode.
