11.4.4 Allocation of sections

When the section automatic allocation option (-auto_section_layout) is not specified, a section is not automatically allocated to the area (address range) corresponding to the relocation attribute specified by the .SECTION, .CSEG, or .DSEG directive. Allocation that avoids exceeding the (64K-1) byte boundary is also not carried out.
Specify a suitable address for allocating each section using the -start option of the linker.
