7.3 Internal Memory Configuration
The internal instruction ROM is located in the internal memory space at address x'40000000 to x'4001FFFF, while
the internal flash memory is located at address x'40000000 to x'4003FFFF and the internal data RAM is located at
address x'00000000 to x'00001FFF. Each is connected to the CPU core independently by a dedicated bus in the
Harvard architecture (in memory extension mode).
Fig. 7-3-1 shows a block diagram of the internal memory in memory extension mode.
