4.7.1
When SCS bits are configured to run from the INTRC,
a clock transition is generated if the system clock is not
already using the INTRC. The event will clear the
OSTS bit and switch the system clock from the primary
system clock (if SCS<1:0> = 00) determined by the
value contained in the configuration bits, or from the
T1OSC (if SCS<1:0> = 01) to the INTRC clock option
and shut-down the primary system clock to conserve
power. Clock switching will not occur if the primary
system clock is already configured as INTRC.

If the system clock does not come from the INTRC
(31.25 kHz) when the SCS bits are changed and the
IRCF bits in the OSCCON register are configured for a
frequency other than INTRC, the frequency may not be
stable immediately. The IOFS bit (OSCCON<2>) will
be set when the INTOSC or postscaler frequency is
stable, after 4 ms (approx.).
After a clock switch has been executed, the OSTS bit
is cleared, indicating a low-power mode and the device
does not run from the primary system clock. The inter-
nal Q clocks are held in the Q1 state until eight falling
edge clocks are counted on the INTRC oscillator. After
the eight clock periods have transpired, the clock input
to the Q clocks is released and operation resumes (see
Figure 4-7).
