Figure 9-3.
• The Power Management Controller provides:
• Includes a 20-bit Periodic Counter with less than 1 µs accuracy
• Includes a 12-bit Interval Overlay Counter
• Real time OS or Linux
• 12-bit key-protected only-once programmable counter
• Windowed, prevents the processor to be in a dead-lock on the watchdog access
• 32-bit Free-running backup counter
• Alarm Register capable to generate a wake-up of the system
