I'm guessing (despite never using a PIC, but scanning throught the 
data sheet now) that the 16C63A is either One Time Programmable 
(OTP), at which point, once you've programmed it once, that's it - no 
more programming.  If your chip has a window on top, you'll need to 
erase it with a UV light box.
