14. Module: Internal Fixed Voltage Reference
15. Module: High Low Voltage Detect (HLVD)
DS80425G-page 6
The FVRST bit of the CVRCON2 register activates
prematurely (Rev. A4 and A7 only).
Work around
Wait an additional 20 µs after FVRST is sensed
high before using the fixed voltage reference.
Enable the FVR by setting the FVREN bit of the
CVRCON2
peripheral that automatically enables the FVR.
Peripherals that automatically enable the FVR
include the Brown-out Reset, the High/Low
Voltage Detect, and the HFINTOSC.
Affected Silicon Revisions
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
peripheral that automatically enables the FVR.
Peripherals that automatically enable the FVR
include the Brown-out Reset, the High/Low
Voltage Detect, and the HFINTOSC.

16. Module: BOR
17. Module: System Clocks
18. Module: POR/BOR
An unexpected Brown-out Reset may occur when
the fixed voltage reference is inactive and BOR is
activated, thereby activating the fixed voltage ref-
erence 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.
Affected Silicon Revisions
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 the device in
Reset below 1.1V.
