S5U1C17001C MANUAL
(C COMPILER PACKAGE FOR S1C17 FAMILY) (Ver. 1.1)
When the -T option is not specified, the ld linker uses the default script shown below for linkage.
OUTPUT_FORMAT("elf32-c17", "elf32-c17", "elf32-c17")

In this script, data will be located from address 0 in order of .bss and .data sections, the vector table,
program codes and constant data will be located from address 0x8000.
Figure 9.4.1.1 shows the memory map after linkage.
