1. Module: Oscillator Configurations
(INTRC and INTOSC)
Summary of Changes
• INTOSC Clock Source
- The Least Significant bit of the OSCTUNE
register – TUN0 (OSCTUNE<0>) – is not
implemented.
implemented.
- As a result, incrementing or decrementing
the OSCTUNE register will not have the
expected, single-step change on the
INTOSC frequency.
expected, single-step change on the
INTOSC frequency.
- When the INTOSC clock source is started,
the IOFS bit (OSCCON <2>) is clear, but it
becomes set in approximately 100
becomes set in approximately 100
μs.
- The INTOSC clock frequency is stable
when the IOFS bit is set.
• INTRC Clock Source
- This 31 kHz, internal RC oscillator source
is a separate, fixed frequency. It is not
tunable.

“OSCTUNE Register” is changed as shown.
When the OSCTUNE register is modified, the INTOSC
frequency will begin shifting to the new frequency. The
INTOSC clock will stabilize within 100
