Incrementing or decrementing the value in the
OSCTUNE register may not have the expected
effect of shifting the INTRC or INTOSC output
frequencies. The OSCTUNE values for which this
happens may vary with temperatures above 70°C.

Date Codes that pertain to this issue:
All engineering and production devices.
At high temperature (above 85°C) or low V
(below 2.5V), the IOFS bit (OSCCON<2>) may not
become set when the internal oscillator block is
selected as the system clock source for any
frequency above 31 kHz (OSCCON<6:4>
The INTOSC output will stabilize at 8 MHz;
however, the IOFS bit may not become set.
Work around
If time critical code is to be executed, it should be
delayed by 1 ms following the operation that
enables the 8 MHz INTOSC output from the
internal oscillator block.

Features that depend on the operation of the
INTRC clock source may be affected. These
include the INTOSC output when exiting from
Sleep mode, the Watchdog Timer (WDT) if
enabled by firmware using the WDTCON register,
Two-Speed Start-ups during Reset or wake-up
from Sleep and the Fail-Safe Clock Monitor
(FSCM) when exiting Sleep mode.
The INTOSC frequency may rise very high (for
example, 9.5 MHz). The WDT and the FSCM may
simply not function. Two-Speed Start-ups may not
occur but execution will start once the primary
clock source becomes ready.
Work around
Several work arounds may be used.
1. Enable the WDT in Configuration register,
