LPC2131/2132/2134/2136/2138
Single-chip 16/32-bit microcontrollers
6.4 Memory map
The LPC2131/2132/2134/2136/2138 memory map incorporates several distinct regions,
as shown in Figure 5.
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 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.
