Nor is the problem with table reads when cold <G>.

1. Module: Core
Performing table read operations above the user
program memory space (addresses over
1FFFFFh) may yield erroneous results at the
extreme low end of the device=92s rated temperature
range (-40=B0C).
=2E...
Date Codes that pertain to this issue:
All engineering and production devices.

So A4 is NOT exempt from this bug.

I guess they forgot that some of us our PIC's in Canadian winters
up north where -40C common.

Yes, what a royal PITA!

May I suggest that people test their units by overclocking them=20
while going through the full temperature range since the problem=20
is 'code sequence dependent'. At least you'll know if you have
a problem that will soon bite you.
