Bit

Default Value

Description

NLOAD

When this bit is set to 1, it indicates that at least one phase entered no load

condition determined by the total active power and apparent power. The phase is

indicated in Bits[2:0] (NLPHASE[x]) in the PHNOLOAD register (see Table 41.)

FNLOAD

When this bit is set to 1, it indicates that at least one phase entered no load

condition based on fundamental active and reactive powers. The phase is indicated

in Bits[5:3] (FNLPHASE[x]) in the PHNOLOAD register (see Table 41).

VANLOAD

When this bit is set to 1, it indicates that at least one phase entered no load

condition based on apparent power. The phase is indicated in Bits[8:6]

(VANLPHASE[x]) in the PHNOLOAD register (see Table 41).

ZXTOVA

When this bit is set to 1, it indicates a zero crossing on Phase A voltage is missing.

ZXTOVB

When this bit is set to 1, it indicates a zero crossing on Phase B voltage is missing.

ZXTOVC

When this bit is set to 1, it indicates a zero crossing on Phase C voltage is missing.

ZXTOIA

When this bit is set to 1, it indicates a zero crossing on Phase A current is missing.

ZXTOIB

When this bit is set to 1, it indicates a zero crossing on Phase B current is missing.

ZXTOIC

When this bit is set to 1, it indicates a zero crossing on Phase C current is missing.

ZXVA

When this bit is set to 1, it indicates a zero crossing has been detected on Phase A

voltage.

ZXVB

When this bit is set to 1, it indicates a zero crossing has been detected on Phase B

voltage.

ZXVC

When this bit is set to 1, it indicates a zero crossing has been detected on Phase C

voltage.

ZXIA

When this bit is set to 1, it indicates a zero crossing has been detected on Phase A

current.

ZXIB

When this bit is set to 1, it indicates a zero crossing has been detected on Phase B

current.

ZXIC

When this bit is set to 1, it indicates a zero crossing has been detected on Phase C

current.

RSTDONE

In case of a software reset command, Bit 7 (SWRST) is set to 1 in the CONFIG register,

or a transition from PSM1, PSM2, or PSM3 to PSM0, or a hardware reset, this bit is set

to 1 at the end of the transition process and after all registers changed value to

default. The IRQ1 pin goes low to signal this moment because this interrupt cannot

be disabled.

SAG

When this bit is set to 1, it indicates one of phase voltages entered or exited a sag

state. The phase is indicated by Bits[14:12] (VSPHASE[x]) in the PHSTATUS register

(see Table 40).

When this bit is set to 1, it indicates an overcurrent event has occurred on one of the

phases indicated by Bits[5:3] (OIPHASE[x]) in the PHSTATUS register (see Table 40).

When this bit is set to 1, it indicates an overvoltage event has occurred on one of the

phases indicated by Bits[11:9] (OVPHASE[x]) in the PHSTATUS register (see Table 40).

SEQERR

When this bit is set to 1, it indicates a negative-to-positive zero crossing on Phase A

voltage was not followed by a negative-to-positive zero crossing on Phase B voltage

but by a negative-to-positive zero crossing on Phase C voltage.

MISMTCH

When this bit is set to 1, it indicates

ISUMLVL

INWV

ISUM

−

, where

ISUMLVL is indicated in the ISUMLVL register.

Reserved

Reserved. This bit is always set to 1.

Reserved

Reserved. This bit is always set to 0.

PKI

When this bit is set to 1, it indicates that the period used to detect the peak value in

the current channel has ended. The IPEAK register contains the peak value and the

phase where the peak has been detected (see Table 34).
