AT91SAM9XE128/256/512 Preliminary
ARM9EJ-S Operating Modes
Minimum interrupt latency is maintained across both ARM state and Java state. Since byte
codes execution can be restarted, an interrupt automatically triggers the core to switch from
Java state to ARM state for the execution of the interrupt handler. This means that no special
provision has to be made for handling interrupts while executing byte codes, whether in hard-
ware or in software.
In all states, there are seven operation modes:
Mode changes may be made under software control, or may be brought about by external inter-
rupts or exception processing. Most application programs execute in User Mode. The non-user
modes, known as privileged modes, are entered in order to service interrupts or exceptions or to
access protected resources.
• User mode is the usual ARM program execution state. It is used for executing most
• Fast Interrupt (FIQ) mode is used for handling fast interrupts. It is suitable for high-speed data
• Interrupt (IRQ) mode is used for general-purpose interrupt handling
• Supervisor mode is a protected mode for the operating system
• Abort mode is entered after a data or instruction prefetch abort
• System mode is a privileged user mode for the operating system
• Undefined mode is entered when an undefined instruction exception occurs
