6.4 Memory map
The LPC2131/32/34/36/38 memory map incorporates several distinct regions, as shown
in Figure 6.
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 6.18
“System control”.
