5.1
If clock switching is enabled, the system clock source at
device Reset is chosen as shown in Table 5-2. If clock
switching is disabled, the system clock source is always
selected according to the oscillator Configuration bits.
Refer to Section 7.0 “Oscillator Configuration” for
further details.

5.2
The Reset times for various types of device Reset are
summarized in Table 5-3. The system Reset signal,
SYSRST, is released after the POR and PWRT delay
times expire.
The time at which the device actually begins to execute
code also depends on the system oscillator delays,
which include the Oscillator Start-up Timer (OST) and
the Phase-Locked Loop (PLL) lock time. The OST and
PLL lock times occur in parallel with the applicable
SYSRST delay times.
The FSCM delay determines the time at which the
FSCM begins to monitor the system clock source after
the SYSRST signal is released.
