## Interrupt Vector Definitions

The file `<cyg/hal/hal_platform_ints.h>` (located at `hal/arm/arm9/at91sam7/VERSION/include/hal_platform_ints.h` in the eCos source repository) contains interrupt vector number definitions for use with the eCos kernel and driver interrupt APIs. The exact set of vectors supported depends on the AT91SAM7 model:
