Device Overview MC9S12XHY-Family
1.3.5 Internal Phase-Locked Loop (IPLL)
⢠Phase-locked-loop clock frequency multiplier
â No external components required
â Reference divider and multiplier allow large variety of clock rates
â Automatic bandwidth control mode for low-jitter operation
â Automatic frequency lock detector
â Conï¬gurable option to spread spectrum for reduced EMC radiation (frequency modulation)
â
1.3.6 Clocks and reset generation(CRG)
⢠COP watchdog
⢠Real time interrupt
⢠Clock monitor
⢠Fast wake up from STOP in self clock mode
1.3.7 System Integrity Support
⢠Power-on reset (POR)
⢠System reset generation
⢠Illegal address detection with reset
⢠Low-voltage detection with interrupt or reset
⢠Real time interrupt (RTI)
⢠Computer operating properly (COP) watchdog
â Conï¬gurable as window COP for enhanced failure detection
â Initialized out of reset using option bits located in ï¬ash memory
⢠Clock monitor supervising the correct function of the oscillator
⢠Temperature sensor
