External reference crystal frequency for the PLL1
1. An externally supplied reference clock should be as free as possible from any phase jitter for the PLL to work
correctly. The PLL is optimized for 4MHz input crystal.

PLL stabilization time 3-40o to +85oC
3. This is the minimum time required after the PLL set-up is changed to ensure reliable operation.
