So RC resets should be hunted down and be terminated.
totally agree.

the ultimate joke is that whreas the SILabs chips have an excellent interanl watchdog, sonme i - eh some one managed to get a "noise suppression capacitor" added on the SILabs devboards effectively converting the (open drain) supervisor to a RC reset.

If you scan the SILabs forum you will find tons of posts "remove that capacitor"

What is even worse, is that many use the devboard schematics as "reference designs" and faithfully put the cap on.

PS re "the SILabs chips have an excellent interanl watchdog" I have found that the internal watchdogs work well on chips with a large analog content and not too well on chips with no/very little analog content. I guess this is due to "when doing analog anyhow" to include a good supervisor is simple, if you have to add this analog function to an otherwise digital chip, you take shortcuts.
