I've not used the 25k22 but do use the 14k22 a bit so guessing they are very similar I have these two tests after setting OSCCON and OSCTUNE btfss osccon,hfiofs ;IRC stable bra $-2 btfss osccon2,hfiofl ;IRC locked bra $-2 When setting up an unfamiliar osc config I'll test it by btg-ing a pin in a= =20 loop with a delay (eg nominal 1ms on/off) to view on the scope / frequency meter to check that it got set correctly Joe=20 ----- No virus found in this message.
