6.4 Memory map
6.5 Interrupt controller
The LPC2131/2132/2138 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
“System
The 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.
