Device Overview MC9S12HY/HA-Family
1.3.6 Internal Phase-Locked Loop (IPLL)
• Phase-locked-loop clock frequency multiplier
— No external components required
— Reference divider and multiplier allow large variety of clock rates
— Automatic bandwidth control mode for low-jitter operation
— Automatic frequency lock detector
— Configurable option to spread spectrum for reduced EMC radiation (frequency modulation)
— Reference clock sources:
– External 4–16 MHz resonator/crystal (XOSC)
– Internal 1 MHz RC oscillator (IRC)
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
— Configurable as window COP for enhanced failure detection
— Initialized out of reset using option bits located in flash memory
• Clock monitor supervising the correct function of the oscillator
• Temperature sensor
1.3.8 Timer (TIM0)
• 8 x 16-bit channels for input capture
• 8 x 16-bit channels for output compare
• 16-bit free-running counter with 7-bit precision prescaler
• 1 x 16-bit pulse accumulator
1.3.9 Timer (TIM1)
• 8 x 16-bit channels for input capture
• 8 x 16-bit channels for output compare
• 16-bit free-running counter with 7-bit precision prescaler
• 1 x 16-bit pulse accumulator
