Responding to: ???'s previous message
Hey Gopal,
Save This Code

1. Try an external oscillator. Like a 4 pin 12MHz crystal. 
Make sure you leave the XTAL2 open and connect the output of
the oscillator to the XTAL1 (pin19- dip package) and see what
happens. 

2. How are you checking the pulse? And out of curiosity, 
how are you clocking your ADC?
