8.2.12 Internal Status (Status) and Interrupt Mask (Mask)

Address: 15 (Status); 26 (Mask)

Default =

1 (Status), 0 (Mask)

The Status register indicates a variety of conditions within the chip. Writing a '1' to a Status register bit will

clear that bit if the condition that set it has been removed. Writing a '0' to any bit has no effect.

The Mask register is used to control the activation of the INT pin. Writing a '1' to a Mask register bit will allow

the corresponding Status register bit to activate the INT pin when set.

DRDY

Data Ready. During conversion, this bit indicates that low-rate results have been updated.

It indicates completion of other commands and the reset sequence.

I1OR (I2OR)

Current Out of Range. Set when the measured current would cause the I1 (I2) register to

overflow.

V1OR (V2OR)

Voltage Out of Range. Set when the measured voltage would cause the V1 (V2) register

to overflow.

CRDY

Conversion Ready. Indicates that sample rate (output word rate) results have been updat-

ed.

I1ROR (I2ROR)

RMS Current Out of Range. Set when RMS current would cause the I1RMS (I2RMS) regis-

ter to overflow.

V1ROR (V2ROR) RMS Voltage Out of Range. Set when RMS voltage would cause the V1RMS (V2RMS) reg-

ister to overflow.

E1OR (E2OR)

Energy Out of Range. Set when average power would cause P1AVG (P2AVG) to overflow.

I1FAULT (I2FAULT)Indicates when a current fault condition has occurred.

V1SAG (V2SAG)

Indicates when a voltage sag condition has occurred.

TUP

Indicates when the Temperature register (T) has been updated.

V1OD (V2OD)

Modulator oscillation has been detected in the voltage1 (voltage2) A/D.

I1OD (I2OD)

Modulator oscillation has been detected in the current1 (current2) A/D.

LSD

Low Supply Detect. Set when the voltage on the PFMON pin falls below the specified low

level. The LSD bit cannot be reset until the voltage rises above the specified high level.

FUP

Frequency Updated. Indicates the Epsilon register has been updated.

Invalid Command. Normally logic 1. Set to 0 when an invalid command is received. It may

also indicate loss of serial command synchronization and the part may need to be re-ini-

tialized.
