of DMA RAM):
System Management:
• Flexible clock options:
- External, crystal, resonator, internal RC
- Fully integrated PLL
- Extremely low jitter PLL
• Power-up Timer
• Oscillator Start-up Timer/Stabilizer
• Watchdog Timer with its own RC oscillator
• Fail-Safe Clock Monitor
• Reset by multiple sources
Power Management:
• On-chip 2.5V voltage regulator
