22M could actually measure between approx. 21M or 23M and still be in spec. A 20M could measure between 19M and 21M.
22M and 20M are practically the same resistor.
Still unsure? Just try it. CGS boards are very easy to desolder components if needed.
I see a 22M at the input pin 3 of the 3900 for the staircase generator. The other end of the 22M is attached to a trimmer wired between +V and 0V. If I were building this, I would simply use a 10M resistor (since that is the highest value I have) and set the trimmer lower.
