The following figure (see Figure 5) depicts the memory layout that is
configured by the Keil monitor for 64 kByte RAM.

Figure 5:

Memory Model for Use with the Keil Monitor (64 kByte RAM)

Note:
When using the von Neumann memory architecture, ensure that the
CODE and XDATA areas within the application program do not
overlap. This is important because otherwise portions of the program
(CODE) will be overwritten by e.g. variables (XDATA), resulting in
an error when executing user code.
