3.2.3
In RC_RUN mode, the CPU and peripherals are
clocked from the internal oscillator block using the
INTOSC multiplexer; the primary clock is shut down.
When using the INTRC source, this mode provides the
best power conservation of all the Run modes, while
still executing code. It works well for user applications
which are not highly timing sensitive or do not require
high-speed clocks at all times.
If the primary clock source is the internal oscillator
block (either INTRC or INTOSC), there are no distin-
guishable
RC_RUN modes during execution. However, a clock
switch delay will occur during entry to and exit from
RC_RUN mode. Therefore, if the primary clock source
is the internal oscillator block, the use of RC_RUN
mode is not recommended.

This mode is entered by setting SCS1 to ‘1’. Although
it is ignored, it is recommended that SCS0 also be
cleared; this is to maintain software compatibility with
future devices. When the clock source is switched to
the INTOSC multiplexer (see Figure 3-3), the primary
oscillator is shut down and the OSTS bit is cleared. The
IRCF bits may be modified at any time to immediately
change the clock speed.
