Hallo,

mir ist es gelungen mit dem Workpad-Demo den Teiler /8 des internen Oscillators auszuschalten.
Optionsliste hab ich angehängt.
Ich habe also das Häkchen an "Divide clock by 8 internally; [CKDIV8=0]" entfernt und nun geht alles.
Trotzdem ist ja noch der interne Oscillator dran.
Bevor ich was schredder: Welche Option muß ich einstellen um einen externen Quarz mit bis zu 20MHz verwenden zu können?

Wäre diese Einstellung richtig:
Ext. Low-Freq. Crystal; Start-up time PWRDWN/RESET: 1K CK/14 CK + 65 ms; [CKSEL=0100 SUT=10]

Besten Dank!
