Energy Out of Range. Set when the calibrated energy value is too large or too small to fit in the

output word.

RMS Voltage Out of Range. Set when the calibrated RMS voltage value is too large to fit in the

output word.

RMS Current Out of Range. Set when the calibrated RMS current value is too large to fit in the

output word.

Power Calculation Out of Range.

Voltage Out of Range. Set when the calibrated voltage value is too large or too small to fit in

the output word.

Current Out of Range. Set when the calibrated current value is too large or too small to fit in the

output word.

General computation error (e.g., divide by 0)

Set when sum of energy is less than zero. Set or cleared at the same time as EOUT.

Indicates that the energy limit has been reached for the energy to frequency conversion, and a

pulse train will be generated on the EOUT pin (if enabled). This bit is cleared automatically when

the energy rate drops below the level that produces a 4 KHz EOUT pin rate. The bit can also

be cleared by writing to the status register. This status bit is set with a maximum frequency of

4 KHz (when MCLK/K is 4.096 MHz).

Data Ready. Set at the end of a calibration or conversion cycle.
