the .rodata section, until another section is declared. Usually, this section will be mapped into a read-only memory at the
stage of linkage.
Example: .section .rodata
(2) .section .data
Declares the start of a data section with an initial value. Statements following this instruction are assembled as those to be
mapped in the .data section, until another section is declared. Usually, this section will be mapped into a read-only
memory at the stage of linkage and data in this section must be copied to a read/ write memory such as a RAM by the
software before using.
Example: .section .data
 Note
