PIC18F87J90 FAMILY
4.2.3
In RC_RUN mode, the CPU and peripherals are
clocked from the internal oscillator; the primary clock is
shut down. This mode provides the best power conser-
vation 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.
This mode is entered by setting the SCS bits to ‘11’.
When the clock source is switched to the INTRC (see
Figure 4-3), the primary oscillator is shut down and the
OSTS bit is cleared.

On transitions from RC_RUN mode to PRI_RUN mode,
the device continues to be clocked from the INTRC
while the primary clock is started. When the primary
clock becomes ready, a clock switch to the primary
clock occurs (see Figure 4-4). When the clock switch is
complete, the OSTS bit is set and the primary clock is
providing the device clock. The IDLEN and SCS bits
are not affected by the switch. The INTRC source will
continue to run if either the WDT or the Fail-Safe Clock
Monitor is enabled.
