The following table shows the ARM-THUMB interworking directives.

  • CODE16
    Tells the assembler that subsequent instructions are to be interpreted as 16-bit (Thumb) instructions.
  • CODE32
    Tells the assembler that subsequent instructions are to be interpreted as 32-bit (ARM) instructions.

  • DATA
    Tells the assembler that the label is a "data-in-code" label; that is, that it defines an area of data within a code segment.

    You must specify this directive ** if you are defining data in a Thumb code area.
