When the offset correction is enabled, the final converged value (after the offset is corrected) will
be the ideal ADC mid-code value (=8192 for P49/48, = 2048 for P29/28). A pedestal can be
added to the final converged value by programming these bits. So, the final converged value will
be = ideal mid-code + PEDESTAL. See "Offset Correction" in application section.
Applies to channel B (only with independent control).
