BSP and Device Driver Development Guide
The gen68340 BSP provides a default Interrupt Vector Table in the
file $BSP_ROOT/start340/start340.s. After the entry
label is the definition of space reserved for the table of
interrupts vectors. This space is assigned the symbolic name
of __uhoh in the gen68340 BSP.
At __uhoh label is the default interrupt handler routine. This
routine is only called when an unexpected interrupts is raised. One can
add their own routine there (in that case there's a call to a routine -
$BSP_ROOT/startup/dumpanic.c - that prints which address caused the
interrupt and the contents of the registers, stack, etc.), but this should
not return.
