Preliminary data sheet
7.3 Memory map
A 16 kB SRAM block serving as a buffer for the Ethernet controller and a 16 kB SRAM
associated with the second AHB bus can be used both for data and code storage, too.
The 2 kB RTC SRAM can be used for data storage only. The RTC SRAM is battery
powered and retains the content in the absence of the main power supply.
The LPC2460 memory map incorporates several distinct regions as shown in
Figure
In addition, the CPU interrupt vectors may be remapped to allow them to reside in boot
ROM or SRAM (see
