4.2.3
In RC_RUN mode, the CPU and peripherals are
clocked from the internal oscillator block using the
INTOSC multiplexer. In this mode, the primary clock is
shut down. When using the LF-INTOSC 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 LF-INTOSC or INTOSC (MF-INTOSC or
HF-INTOSC) – there are no distinguishable differences
between the PRI_RUN and RC_RUN modes during
execution. Entering or exiting RC_RUN mode,
however, causes a clock switch delay. Therefore, if the
primary clock source is the internal oscillator block,
using RC_RUN mode is not recommended.

This mode is entered by setting the SCS1 bit to ‘1’. To
maintain software compatibility with future devices, it is
recommended that the SCS0 bit also be cleared, even
though the bit is ignored. When the clock source is
switched to the INTOSC multiplexer (see Figure 4-3),
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.
