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.
Date Codes that pertain to this issue:
All engineering and production devices.
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 beyond which
this happens may vary with temperatures above
70°C.

The Buffer Full flag bit (BF) of the SSPSTAT regis-
ter (SSPSTAT<0>) may be inadvertently cleared,
even when the SSPBUF register has not been
read. This will occur only when the following two
conditions occur simultaneously:
• The four Least Significant bits of the BSR
• Any instruction that contains C9h in its 8 Least

Identified work arounds will involve setting the
contents of BSR<3:0> to some value other than
0Fh.
In addition to those proposed below, other solutions
may exist.
