2.2 LPC2141/2142/2144/2146/2148 memory re-mapping and boot block
2.2.1 Memory map concepts and operating modes
The basic concept on the LPC2141/2/4/6/8 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 Block 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
