** \brief Interrupt vectors
**
** The list below describes all available interrupt sources,
** a table containing the real interrupt service routines can
** be stored in the ARC aux. register 0x0203.
**
** The first three interrupt vectors are non-maskable, their
** priorty is high.
** All other interrupts are maskable and the priority can be set
** either to medium (1) or low (2).
