6.4 Memory map
The LPC2292/LPC2294 memory maps incorporate several distinct regions, as shown
in the following figures.
In addition, the CPU interrupt vectors may be re-mapped to allow them to reside in
either Flash memory (the default) or on-chip static RAM. This is described in
Section
6.21 “System control”
.
6.5 Interrupt controller
The Vectored Interrupt Controller (VIC) accepts all of the interrupt request inputs and
categorizes them as FIQ, vectored IRQ, and non-vectored IRQ as defined by
programmable settings. The programmable assignment scheme means that priorities
of interrupts from the various peripherals can be dynamically assigned and adjusted.
