Phase Locked Loop (IPLL) frequency multiplier with internal filter
— Reference divider
— Post divider
— Configurable internal filter (no external pin)
— Optional frequency modulation for defined jitter and reduced emission
— Automatic frequency lock detector
— Interrupt request on entry or exit from locked condition
— Self Clock Mode in absence of reference clock
System Clock Generator
— Clock Quality Check
— User selectable fast wake-up from Stop in Self-Clock Mode for power saving and immediate
— Clock switch for either Oscillator or PLL based system clocks
Computer Operating Properly (COP) watchdog timer with time-out clear window.
System Reset generation from the following possible sources:
— Power on reset
— Low voltage reset
