.noinit
In this section:
Description
Holds static and global __no_init variables.
A companion section called .iar.noinitinfo is generated for each section of this type. This additional section is only used for instructing the linker to ignore the .noinit section and it will not be included in your application. This mechanism works even if the section is renamed, or is generated using #pragma location.
