+/*************************************************************************
+ * Exception Vector Table
+ *
+ * This could have gone in the cpu soure tree, but the whole point of
+ * Nios is customization -- and polluting the cpu source tree with
+ * board-specific ifdef's really defeats the purpose, no? With this in
+ * the board-specific tree, each board has the freedom to organize
+ * vectors/traps, etc anyway it wants. The init code copies this table
+ * to the proper location.
+ *
+ * Each board can do what it likes here. But there are four "standard"
+ * handlers availble:
+ *
+ * _cwp_lolimit -Handles register window underflows.
+ * _cwp_hilimit -Handles register window overflows.
+ * _timebase_int -Increments the timebase.
+ * _def_xhandler -Default exception handler.
+ *
+ * _timebase_int handles a Nios Timer interrupt and increments the
+ * timestamp used for the get_timer(), reset_timer(), etc. routines. It
+ * expects the timer to be configured like the standard-32 low priority
+ * timer.
+ *
+ * _def_xhandler dispatches exceptions/traps via the external_interrupt()
+ * routine. This lets you use the irq_install_handler() and handle your
+ * interrupts/traps with code written in C.

+/*************************************************************************
+ * Exception Vector Table
+ *
+ * This could have gone in the cpu soure tree, but the whole point of
+ * Nios is customization -- and polluting the cpu source tree with
+ * board-specific ifdef's really defeats the purpose, no? With this in
+ * the board-specific tree, each board has the freedom to organize
+ * vectors/traps, etc anyway it wants. The init code copies this table
+ * to the proper location.
+ *
+ * Each board can do what it likes here. But there are four "standard"
+ * handlers availble:
+ *
+ * _cwp_lolimit -Handles register window underflows.
+ * _cwp_hilimit -Handles register window overflows.
+ * _timebase_int -Increments the timebase.
+ * _def_xhandler -Default exception handler.
+ *
+ * _timebase_int handles a Nios Timer interrupt and increments the
+ * timestamp used for the get_timer(), reset_timer(), etc. routines. It
+ * expects the timer to be configured like the standard-32 low priority
+ * timer.
+ *
+ * _def_xhandler dispatches exceptions/traps via the external_interrupt()
+ * routine. This lets you use the irq_install_handler() and handle your
+ * interrupts/traps with code written in C.
