issued, when the CF1 pin goes

from a high to low state.

REVPSUM2

CF2 Polarity Sign Change. This

bit is set to indicate if the

CF2 polarity changed sign. See

REVPSUM1.

0x0

R/W1C

REVPSUM1

CF1 Polarity Sign Change. This

bit is set to indicate if the

CF1 polarity changed sign. For

example, if the last CF1 pulse

was positive active energy

and the next CF1 pulse is

negative active energy, then

REVPSUM1 bit is set. This bit

is updated when the CF1 pin

goes from high to low.

0x0

R/W1C

REVAPC

Phase C Active Power Sign

Change. This bit indicates if

the phase C active power has

changed sign. See REVAPA.

0x0

R/W1C

REVAPB

Phase B Active Power Sign

Change. This bit indicates if

the phase B active power has

changed sign. See REVAPA.

0x0

R/W1C

REVAPA

Phase A Active Power Sign

Change. This bit indicates

if the phase A active

power has changed sign.

This bit is updated when

the power values in the

xWATT_ACC registers update,

after (EGY_TIME + 1)

milliseconds or half-line cycles.

0x0

R/W1C

EGYRDY

Energy Data Ready. This

bit is set when the

accumulated energy values

(xWATTHR, xVAHR … ) are

updated, after (EGY_TIME +

1) milliseconds or half-line

cycles, which depends on the

EGY_TMR_MODE bit in the

EP_CFG register.

STATUS1

ZXAUX5

Auxiliary 5 Channel Zero

Crossing Detected. This bit is

set to indicate a zero crossing

is detected on the AUX5

channel.

0x0

R/W1C

ZXAUX4

Auxiliary 4 Channel Zero

Crossing Detected. This bit is

set to indicate a zero crossing

is detected on the AUX4

channel.

0x0

R/W1C

ZXAUX3

Auxiliary 3 Channel Zero

Crossing Detected. This bit is

set to indicate a zero crossing

0x0
