MEMORY MAPS
The LPC2119/2129/2292/2294 incorporates several distinct memory regions, shown in the following figures. Figure 2 shows the
overall map of the entire address space from the user program viewpoint following reset. The interrupt vector area supports
address re-mapping, which is described later in this section.
