Description
Holds static and global initialized variables that have the memory attribute __saddr and can be accessed via 4-bit offsets from the EP register. In object files, this includes the initial values. When the linker directive initialize by copy is used, a corresponding .tdata4_init section is created for each .tdata4 section, holding the possibly compressed initial values.
