(e) Example of memory allocation and address specification at link time
When writing a program to ROM, whether sections are allocated to RAM or to ROM is
determined by whether there are initial values and whether write operations are enabled.
When writing the sections of a C/C++ program to ROM, sections are allocated to ROM or
to RAM as follows.
Sections which have initial values and can be altered on program execution, such as
initialized data areas, are placed in ROM at link time and copied to RAM at the start of
program execution. Hence the rom option of the optimizing linkage editor must be used to
reserve the duplicate memory area both in ROM and in RAM. For an example of this, refer
to "(e) Example of memory allocation and address specification at link time" below. Initial
settings for sections to be copied from ROM to RAM are explained in section 9.2.2 (2),
Initial settings (PowerON_Reset).
When creating an absolute load module, addresses are specified per allocated area for each
section using an optimizing linkage editor option or a subcommand. Below, examples of
static memory allocation and of address specification at link time are explained.
Figure 9.4 shows an example of allocation of a static memory area in H8S/2600 advanced
mode.
