'PIC14000 Code Protection'

I've managed to destroy several PIC14000JW devices recently by inadvertently
enabling code protection with the Picstart plus.  There are several archive
references from others who have had this problem and references to potential
errors in the PIC14000 data sheet and/or the AN624 include file.  Can anyone
offer advice about how one might circumvent the errata and avoid
unintentional enabling of code protection?

Thanks in advance

Use the __config directive in MPASM to set code protect disabled, so
Picstart will default to c/p off
