• The potential for failures increases over the life
• The potential for failures is highest at low V
• The potential for failures depends on the set-
Setting a PORTB Interrupt-on-change enable bit of
the IOCB register while the corresponding PORTB
input is high will cause an RBIF interrupt.
Work around
Set the IOCB bits to the desired configuration then
read PORTB to clear the mismatch latches.
Finally, clear the RBIF bit before setting the RBIE
bit.

After extended stress the Most Significant bit
(MSb) of the ADC conversion result can become
stuck at ‘0’. Conversions resulting in code 511 or
less are still accurate, but conversions that
should result in codes greater than 511 are
instead pinned at 511.
The potential for failures is a function of several
factors:
of the part. No failures have ever been seen for
accelerated stress estimated to be equivalent
to 34 years at room temperature. The failure
rate after accelerated stress estimated to be
equivalent to 146 years at room temperature
can be as high as 10% for V
to failure will decrease as the operating temper-
ature increases.
