Chapter 2: LPC24XX Memory mapping
Figure 8 and Table 2–17 show different views of the peripheral address space. Both the
AHB and APB peripheral areas are 2 megabyte spaces which are divided up into 128
peripherals. Each peripheral space is 16 kilobytes in size. This allows simplifying the
address decoding for each peripheral.
