I am trying to run 89c51 it does not seem to start, as my test code is to toggle port in while(1) loop.
1. I had checked reset pin on scope its low.
2. I put cr0 probe on 10x.
Then I put probe on XTAL1, I don't see anything
I think crystal is not running.
I had changed crystal/mcu also but no change in behaviour.
Edit; I am usinh 15Mhz crystal with 30pf load cal
