- * \brief System IRQ handler for Atmel AT91 ARM7 processors.
- *
- * In Atmel AT91 ARM7TDMI processors, there are various
- * peripheral interrupt sources.
- * In general, every source has its own interrupt vector, so it
- * is possible to assign a specific handler for each interrupt
- * independently.
- * However, there are a few sources called "system sources" that
- * share a common IRQ line and vector, called "system IRQ".
- * So a unique system IRQ dispatcher is implemented here.
- * This module also contains an interface to manage every source
- * independently. It is possible to assign to every system IRQ
- * a specific IRQ handler.
- *
- * \see sysirq_setHandler
- * \see sysirq_setEnable
