® This corresponds to row 14 in the table, behaviour similar to Fig. 1

As a special (and rare) case instead of an offset correction after edge number 5, a further

(extra) PGA switching could occur before edge number 5. PGA switching inhibits an

immediate offset update. It can happen if one of the signal peaks is exactly at a PGA

switching threshold (speed-ADC overflow). In this case the offset update (switching from

uncalibrated mode to calibrated mode) would be delayed by two to three further edges. The

referring phase shifts of the example would then be as follows:
