I didn't mean to say that the condition was not critical, i meant that the
interrupt generated is used for notification purposes, and in its current
state the interrupt handler only provides information rather than taking
measures due to the condition. The condition in this case is handled
automatically by the hardware and we just receive notification via an
interrupt getting triggered. However i have taken your suggestion and
moved the vector.
