If I remember my initial reading of 12C5XX app notes, you should save the
OSCCAL value by reading it with your programmer BEFORE you erase it.  When
you reprogram the device, reprogram the old OSCCAL value with it.

Subject:        OSCCAL and UV erase

PIC-nikkers:

What happens to the OSCCAL number when you UV erase a windowed
PIC12C508?  Is the OSCCAL even programmed into windowed parts in the
first place?     I've noticed that piezo beepers hooked up to two
different windowed parts usually have different tones, meaning the
oscillators must run at different freq's.
