#185552 - Additional pull-ups are sufficient in many cases...
Responding to: Erik Malund's previous message
In many cases an additional pull-up of 4k7...10k at critical ports is entirely sufficient. There are nice resistor arrays on the market, so, only very little board space is wasted by the additional pull-ups.
