Description
This bit is set if any of the ADE status flags that are enabled to generate an ADE interrupt are set. This bit is
automatically cleared when all of the enabled ADE status flags are cleared.
Reserved.
Logic 1 indicates that the reactive power sign has changed according to the configuration of the ACCMODE register.
Logic 1 indicates that the active power sign has changed according to the configuration of the ACCMODE register.
Logic 1 indicates that an interrupt has been caused by apparent power no-load detected. This interrupt is also
used to reflect the part entering the I
Logic 1 indicates that an interrupt has been caused by reactive power no-load detected.

Configuration bit to select event that triggers a reactive power sign interrupt. If set to 0, VARSIGN
interrupt occurs when reactive power changes from positive to negative. If set to 1, VARSIGN interrupt
occurs when reactive power changes from negative to positive.
Configuration bit to select event that triggers an active power sign interrupt. If set to 0, APSIGN interrupt
occurs when active power changes from positive to negative. If set to 1, 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.
