15. Module: High Low Voltage Detect (HLVD)
16. Module: BOR
17. Module: System Clocks

The IVRST bit of the HLVDCON register activates
prematurely (Rev. A4 and A7 only).
Work around
Wait an additional 20 µs after IVRST is sensed
high before using the fixed voltage reference.
Enable the FVR by setting the FVREN bit of the
CVRCON2 register before activating any periph-
eral that automatically enables the FVR. Peripher-
als that automatically enable the FVR include the
Brown-out Reset, the High/Low Voltage Detect,
and the HFINTOSC.
Affected Silicon Revisions
An unexpected Brown-out Reset may occur when
the fixed voltage reference is inactive and BOR is
activated, thereby activating the fixed voltage
reference simultaneously. This error is caused by
a premature FVRST stable flag (Rev. A4 and A7
only).
Work around
Enable the FVR by setting the FVREN bit of the
CVRCON2 register and then wait an additional
20 µs after FVRST is sensed high before
enabling BOR. Brown-out disable in Sleep mode
with automatic enable on wake-up cannot be used.
Affected Silicon Revisions
HFINTOSC output frequency is 16 MHz ± 3%
25°C to 85°C.
Work around
None.

18. Module: POR/BOR
19. Module: POR
20. Module: POR
The POR rearm voltage may be below the low end
of the BOR range causing unexpected code
execution below the BOR range.
Work around
Use external power monitor to hold device in
Reset below 1.1 Volts.
Affected Silicon Revisions
The POR may release around 0.8 volts (below the
POR rearm voltage of 1.2V nominal) when V
rises from below either 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
Affected Silicon Revisions
The part may hang in the Reset state when V
rises to the operating range at a rate faster than
7500 volts per second. Recovery from the hung
state is possible only by first lowering V
0.3V followed by raising V
range.
Work around
Slow V

increasing the V
bypassing should remain on the pin side of the
series resistor.
