2. LPC2119/2129/2292/2294 MEMORY ADDRESSING
MEMORY MAPS
The LPC2119/2129/2194/2292/2294 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.
