Core Timer Interrupt

The Core Timer Interrupt (
reaches zero. For more information about the core timer, see the Hard-
ware Reference Manual for your processor.

General-purpose Interrupts (IVG7-IVG15)

General-purpose interrupts are used for any event that requires processor
attention. For instance, a DMA controller may use them to signal the end
of a data transmission, or a serial communications device may use them to
signal transmission errors.
Software can also trigger general-purpose interrupts by using the
