5. LPC2400 memory re-mapping and boot ROM

User manual
5.1 Memory map concepts and operating modes
The basic concept on the LPC2400 is that each memory area has a "natural" location in
the memory map. This is the address range for which code residing in that area is written.
The bulk of each memory space remains permanently fixed in the same location,
eliminating the need to have portions of the code designed to run in different address
ranges.
Because of the location of the interrupt vectors on the ARM7 processor (at addresses
0x0000 0000 through 0x0000 001C, as shown in
Boot ROM and SRAM spaces need to be re-mapped in order to allow alternative uses of
interrupts in the different operating modes described in
interrupts is accomplished via the Memory Mapping Control feature
