2.1.1
The main features of this block are:
Freescale Semiconductor
•
•
•
•
•
Phase locked loop (PLL) frequency multiplier
— Reference divider
— Automatic bandwidth control mode for low-jitter operation
— 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
— Illegal address reset
— COP reset
— Loss of clock reset
— External pin reset
Real-time interrupt (RTI)
