If the main oscillator is configured for HS4 (PLL) mode
with SCS1 bit set to ‘1’, an oscillator start-up time
(T
occur. The PLL time-out is typically 2 ms and allows the
PLL to lock to the main oscillator frequency. A timing
diagram indicating the transition from the Timer1 oscil-
lator to the main oscillator for HS4 mode is shown in
Figure 2-8.
If the main oscillator is configured for HS4 (PLL) mode,

put is not used, so the system oscillator will come from
OSC1 directly and additional delay of T
required. A timing diagram indicating the transition from
the Timer1 oscillator to the main oscillator for HS4
mode is shown in Figure 2-9.
If the main oscillator is configured in the RC or EC
modes, there is no oscillator start-up time-out. Opera-
tion will resume after eight cycles of the main oscillator
have been counted. A timing diagram indicating the
transition from the Timer1 oscillator to the main oscilla-
tor for RC and EC modes is shown in Figure 2-10.
