__iar_tls$$INITDATA
In this section:
Description
Holds initial values for the thread-local storage area. The main use for this section is to copy it to a thread’s thread-local storage area when the thread is created. The difference between the size of this section and the total size of the thread-local storage area (the section __iar_tls$$DATA) is the number of bytes in the thread-local storage area that should be initialized to zero.
This section is created by the linker if the linker option ‑‑threaded_lib is used.
