12.3.3 Output Clock Stabilization Time
Figure 12-14 shows the 32KCLKOUT and HFCLKOUT clock stabilization time.
NOTE: Tstartup, Delay1, and Delay2 depend on the boot mode (see Section 4.5, Power Management).
NOTE: Ensure that the high frequency oscillator start-up time is in spec for the boot mode used. During power-up the internal
delay, Delay1 above is fixed (5.2 ms and 5.3 ms depending on boot mode). The start-up time for the oscillator must
be less than the fixed delay.
