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

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
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).
