If the code protection bit has not been programmed,
the on-chip program memory can be read out for
verification purposes.
The first 64 locations can be read by the PIC12C5XX
regardless of the code protection bit setting.
The last memory location cannot be read if code protection
is enabled on the PIC12C508/509.
The last memory location can be read regardless of the
code protection bit setting on the PIC12C508A/509A/
