How can a section be divided into multiple sections? Currently my program is sectioned into 001000H to 00F00FH and 010000H to

01EFFFFH. But I want to place my program from 130000H as well.

One continuous section can not be divided into multiple separate sections. But each individual function can be placed in different

sections.

For example, special functions can be placed in a particular section and the section can be assigned to 13000h with .org.

[Procedure]

Pick up the functions you want to place in address 13000h (external ROM) as a separate file. The file does not need to be a

single file.

In the top of the file, insert statement "#pragma SECTION program mysection (modified section name)". (You can use any

section name.)

* With this step, the program section is changed to mysection_N and mysection_F.

* This procedure is applied just for the program section. For the data section, you need to perform the same step separately.

Add address data of mysection_N and mysection_F to section.inc.

* Standard libraries are placed in section program_F. We recommend keeping the default section until you confirm that no

data remains in sections program_N and program_F. You can confirm them in the map file.

[Assumptions]

Please refer to the [NC77 Memory Allocation] section in the User's Manual for details concerning naming conventions

of pre-defined sections.

❍

The near-defined functions are placed in section program_N as the defaultsetting. In the same manner, far-defined

functions are placed in section program_F.

❍

When statement "#pragma SECTION program mysection" is used, the near-defined function is placed in my section_N

and the far_defined function is placed in mysection_F.
