2.6.2
PIC18C601/801 devices contain circuitry to prevent
"glitches" when switching between oscillator sources.
Essentially, the circuitry waits for eight rising edges of
the clock source that the processor is switching to.
This ensures that the new clock source is stable and
that its pulse width will not be less than the shortest
pulse width of the two clock sources.
A timing diagram indicating the transition from the main
oscillator to the Timer1 oscillator is shown in Figure 2-6.
The Timer1 oscillator is assumed to be running all the
time. After the SCS0 bit is set, the processor is frozen
at the next occurring Q1 cycle. After eight synchroniza-
tion cycles are counted from the Timer1 oscillator, oper-
ation resumes. No additional delays are required after
the synchronization cycles.

The sequence of events that takes place when switch-
ing from the Timer1 oscillator to the main oscillator will
depend on the mode of the main oscillator. In addition
to eight clock cycles of the main oscillator, additional
delays may take place.
If the main oscillator is configured for an external crys-
tal (HS, LP), the transition will take place after an oscil-
lator start-up time (T

lator to the main oscillator for HS and LP modes is
