Interrupt Flag

Description

ADEIRQFLAG

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

Reserved.

FAULTSIGN1

Logic one indicates that the Fault mode has changed according to the configuration of

the ACCMODE register

VARSIGN10

Logic one indicates that the reactive power sign changed according to the configuration

of ACCMODE register

APSIGN

Logic one indicates that the active power sign changed according to the configuration of

ACCMODE register

VANOLOAD

Logic one indicates that an interrupt was caused by apparent power no-load detected.

This interrupt is also used to reflect the part entering the IRMS No load mode.

RNOLOAD2

Logic one indicates that an interrupt was caused by reactive power no-load detected.

APNOLOAD

Logic one indicates that an interrupt was caused by active power no-load detected.
