Hi again, I'm trying to configure my own F628 watchdog timer by letting timer 1 = overflow in about 2 hours, counting pulses from it's own internal = oscillator with an external 220k R and 10uF C attached. The osc doesn't = run, while it does with a 4093 (=3D higher part count =3D bad). Is this = oscillator designed to work with RCs or does it only support a 32.768 = kHz watch Xtal?
