Clocks and Reset Generator (CRGV4)
4.1
This specification describes the function of the clocks and reset generator (CRGV4).
4.1.1
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
— CPU interrupt on entry or exit from locked condition
— Self-clock mode in absence of reference clock
System clock generator
— Clock quality check
— Clock switch for either oscillator- or PLL-based system clocks
— User selectable disabling of clocks during wait mode for reduced power consumption
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
— COP reset
— Loss of clock reset
— External pin reset
Real-time interrupt (RTI)
