microcontroller troubleshooting
I have an atmel microcontroller circuit and it is not working
I probe the XIN/XOUT lead (crystal input) but could not see a 20mhz signal on my scope.. I checked VDD and ground connector and they are good.
Is it a bad chip or is there something else I can check?
Thank you
