Figure 9-3. SAM9260 Power Management Controller Block Diagram
9.6
Periodic Interval Timer
Includes a 20-bit Periodic Counter, with less than 1 s accuracy
Includes a 12-bit Interval Overlay Counter
Real Time OS or Linux/Windows CE compliant tick generator
9.7
Watchdog Timer
16-bit key-protected only-once-Programmable Counter
Windowed, prevents the processor being in a dead-lock on the watchdog access
9.8
Real-time Timer
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 Controller
9.9
General-purpose Back-up Registers
Four 32-bit backup general-purpose registers
9.10 Advanced Interrupt Controller
Controls the interrupt lines (nIRQ and nFIQ) of the ARM Processor
Thirty-two individually maskable and vectored interrupt sources
Source 0 is reserved for the Fast Interrupt Input (FIQ)
Source 1 is reserved for system peripherals (PIT, RTT, PMC, DBGU, etc.)
Programmable Edge-triggered or Level-sensitive Internal Sources
Programmable Positive/Negative Edge-triggered or High/Low Level-sensitive
Three External Sources plus the Fast Interrupt signal
