TABLE 6-3:
6.3.1
The oscillator start-up circuitry and its associated delay
timers are not linked to the device Reset delays that
occur at power-up. Some crystal circuits (especially
low-frequency crystals) will have a relatively long
start-up time. Therefore, one or more of the following
conditions is possible after SYSRST is released:
• The oscillator circuit has not begun to oscillate.
• The Oscillator Start-up Timer has not expired (if a
• The PLL has not achieved a lock (if PLL is used).
The device will not begin to execute code until a valid
clock source has been released to the system. There-
fore, the oscillator and PLL start-up delays must be
considered when the Reset delay time must be known.

If Two-speed Start-up is enabled, regardless of the primary oscillator selected, the device starts with FRC

If the FSCM is enabled, it will begin to monitor the
system clock source when SYSRST is released. If a
valid clock source is not available at this time, the
device will automatically switch to the FRC oscillator
and the user can switch to the desired crystal oscillator
in the Trap Service Routine (TSR).
