10.6 Phase Locked Loop Timing
10.7 Relaxation Oscillator Timing
1. An externally supplied reference clock should be as free as possible from any phase jitter for the PLL to work correctly. The PLL
2. The core system clock will operate at 1/6 of the PLL output frequency.
3. This is the time required after the PLL is enabled to ensure reliable operation.
4. This is measured on the CLKO signal (programmed as System clock) over 264 System clocks at 32MHz System clock frequency
1. Output frequency after factory trim.
2. This is the time required from Standby to Normal mode transition.
