lates due to an input above full scale. The level at which the modulator oscillates is significantly
higher than the voltage channel’s differential input voltage (current) range.
Note: The IOD and VOD bits may be ‘falsely’ triggered by very brief voltage spikes from the
power line. This event should not be confused with a DC overload situation at the inputs,
when the IOD and VOD bits will re-assert themselves even after being cleared, multiple
times.
LSD
FUP
IC
Low Supply Detect. Set when the voltage at the PFMON pin falls below the low-voltage thresh-
old (PMLO), with respect to AGND pin. The LSD bit cannot be reset until the voltage at PFMON
pin rises back above the high-voltage threshold (PMHI).
Epsilon Updated. Indicates completion of a line frequency measurement and update of Epsilon.
Invalid Command. Normally logic 1. Set to logic 0 if an invalid command is received or the Sta-
tus Register has not been successfully read.

The AC Offset Registers (V ACoff , I ACoff ) are initialized to zero on reset, allowing for uncalibrated normal operation.
AC Offset Calibration updates these registers. This sequence lasts approximately (6N + 30) ADC cycles (where
N is the value of the Cycle Count Register ). DRDY will be asserted at the end of the calibration. These values
may be read and stored for future system AC offset compensation. The value is represented in two's comple-
ment notation in the range of -1.0 ? V ACoff , I ACoff ? 1.0, with the binary point to the right of the MSB
