Certain combinations of code sequence, code
placement, V
cause a corrupted read of fetched instructions or
data. A corrupted instruction fetch will cause the
part to execute an incorrect instruction with
unpredictable results.
Microchip cannot predict which combinations of
these conditions will cause this failure.
If this failure mechanism exists in your system, it
should become evident during statistically signifi-
cant preproduction testing, using your particular
code sequence and placement, across multiple
date codes.
Preproduction testing should exercise all the func-
tions of your application across system variables.
Any changes to code should be tested in the same
manner prior to being implemented.
