Crystal Monitor Time-out
The time-out Table 21 shows the delay for the crystal monitor to trigger when the clock stops, either at the high
or at the low level. The corresponding clock period with an ideal 50% duty cycle is twice this time-out value.
3.8.5
Clock Quality Checker
The timing for the clock quality check is derived from the oscillator and the VCO frequency range in
Table 20. These numbers define the upper time limit for the individual check windows to complete.

NOTES:
1. If CLKSEL[PLLSEL] is set then the system clock (fSYS) is equal to fVCO, otherwise it is equal to fOSC (table Table 19,
J1a or J1b). Throughout this document, tSYS is used to specify a unit of time equal to 1 ÷ fSYS.

C PLLON Total Stabilization delay (Auto Mode) 3
3. PLL stabilization delay is highly dependent on operational requirement and external component values (for
example, crystal and XFC filter component values). Notes 4 and 5 show component values for a typical
configurations. Appropriate XFC filter values should be chosen based on operational requirement of system.
