The POR may release around 0.8V (below the
POR rearm voltage of 1.2V, nominal) when V
rises from below 0.60V (when BOR is not enabled)
or 0.33V (when BOR is enabled).
Work around
Use Power-up Timer when operating with the EC,
EXTRC or HFINTOSC oscillator modes. Ensure
that V
time.
Affected Silicon Revisions
The part may hang in the Reset state when V
rises to the operating range at a rate faster than
7500V per second. Recovery from the hung state
is possible only by first lowering V
followed by raising V
Work around
Slow V
between the voltage supply and the V
increasing the V
bypassing should remain on the pin side of the
series resistor.
Affected Silicon Revisions
EC mode operation is limited to a maximum of
48 MHz (Rev. A4 and A7 only).
Work around
Divide external clock by 4 and use HS-PLL Clock
mode for external clocking above 48 MHz.

22. Module: Comparators
23. Module: Data EEPROM Memory
24. Module: Program Flash Memory
When the CxON bit is clear, the output from the
comparator will be properly forced to zero, but the
CxPOL bit will improperly have no effect on the
CxOUT bit. This prevents presetting the compara-
tor change-on-interrupt mismatch latches as
described in the data sheet.
Work around
Configure one of the unused comparator input
channels as a digital output. Use that digital output
to manipulate the comparator output to the desired
CxOUT non-interrupt level. When the comparator
is then set to the desired inputs, the mismatch
latches will be preset to the non-interrupt level and
the CxIF flag can then be cleared.
Affected Silicon Revisions
The write/erase endurance of Data EE Memory is
limited to 10K cycles.
Work around
Use error correction method that stores data in
multiple locations.
Affected Silicon Revisions
The write/erase endurance of the PFM is limited to
1K cycles when V
degrades when V
Work around
For data tables in program Flash memory use
error correction method that stores data in multiple
locations.
