I have read many post but I do not still have the following thing clear
if I did not save the value of the direction 0x3FF (value of factory of the oscillator), how can I obtain it again.
I can read the pic, but if attempt to record it gives me the following error:
program error:
program: address=0000 buffer=3000 device=0000
thanks

All the programmers and software that I have used protect (or try to) this location. They won't let you program it. I have fooled the software by telling it that I was programming a different device. Search the forum and you should find the post. The only way to get back the value is through trial and error. You will have to write a program to toggle a pin and then measure the pulse width and then adjust the value until to achieve the accuracy that you want.
