HI All
Can anyone explain why my 622 osc can not be seen on a scope. Running
the 622 at 500hz I can see quite well my osc running, put the 4MHz osc
and nothing, although it appears that the chip runs as it sedns a test
message. Ionly thing i see is a sine/square wave of about 0.1vp-p at the
osc frequency. Other pics can be displayed fine at this frequency, why
not the 622?
Also hasi remember a while back mention of pulling the osc caps to 5v
instead of 0V how reliable is this ? what side effects occur?
