AT91SAM9G20
Figure 9-3.
• Includes a 20-bit Periodic Counter, with less than 1 µs accuracy
• Includes a 12-bit Interval Overlay Counter
• Real Time OS or Linux
• 16-bit key-protected only-once-Programmable Counter
• Windowed, prevents the processor being in a dead-lock on the watchdog access
• Real-time Timer 32-bit free-running back-up Counter
• Integrates a 16-bit programmable prescaler running on slow clock
• Alarm Register capable of generating a wake-up of the system through the Shutdown
• Four 32-bit backup general-purpose registers
• Controls the interrupt lines (nIRQ and nFIQ) of the ARM Processor
• Thirty-two individually maskable and vectored interrupt sources
