Clocking Structure
- High-Precision Internal
Oscillator Block (HFINTOSC):
- Selectable frequencies up to 32 MHz
- ±2% at calibration
- Active Clock Tuning of HFINTOSC for improved accuracy
- Internal 31 kHz Oscillator (LFINTOSC)
- External 32 kHz Secondary Oscillator (SOSC)
- External High-Frequency Clock
Input:
- Three Crystal/Resonator modes
- Two External Clock (EC) Power modes
- 4x PLL available for external sources
- Fail-Safe Clock Monitor:
- Allows for operational recovery if the external clock source stops
- Oscillator Start-up Timer (OST):
- Ensures the stability of crystal oscillator sources
