.data simply selects the ".data" section.

Look at the ".section" pseudo-op.  The conventional name for the read
only data section is ".rodata".  You can pick a different name; a lot
of this is just a matter of what the linker scripts do with sections.
.rodata is handled as read-only data by the default scripts, so that's
a good choice.
