On transitions from SEC_RUN mode to PRI_RUN
mode, the peripherals and CPU continue to be clocked
from the Timer1 oscillator while the primary clock is
started. When the primary clock becomes ready, a
clock switch back to the primary clock occurs (see

Figure 3-2). When the clock switch is complete, the
T1RUN bit is cleared, the OSTS bit is set and the
primary clock would be providing the clock. The IDLEN
and SCS bits are not affected by the wake-up; the
Timer1 oscillator continues to run.
