Selects whether the REVRPx bit follows the sign of

the total or fundamental reactive power.

0x0

R/W

0 Total reactive power.

1 Fundamental reactive power.

RD_RST_EN

Set this bit to enable the energy register read with

reset feature. If this bit is set, when one of the

xWATTHR, xVAHR, xVARHR and xFVARHR register is

read, it is reset and begins accumulating energy

from zero.

0x0

R/W

EGY_LD_ACCUM

If this bit = 0, the internal energy register is added

to the user accessible energy register. If the bit is

set, the internal energy register overwrites the

user accessible energy register when the EGYRDY

event occurs.

EGY_TMR_MODE

This bit determines whether energy is

accumulated based on the number of 4 kSPS

samples or zero crossing events configured in the

EGY_TIME register.

0x0

R/W

0 Accumulate energy based on 4 kSPS samples.

1 Accumulate energy based on the zero crossing

selected by the ZX_SEL bits in the ZX_LP_SEL

EGY_PWR_EN

Set this bit to enable the energy and power

accumulator, when the run bit is also set.
