How do I switch from Thumb to ARM mode? To direct the assembler to generate ARM or Thumb instruction encodings, you must set the assembler mode using an ARM or THUMB directive . To generate ThumbEE code, use the THUMBX directive. Assembly code using CODE32 and CODE16 directives can still be assembled, but ARM recommends using ARM and THUMB for new code. fileslib. What is Thumb mode? Thumb mode allows for code to be smaller, and can potentially be faster if the target has slow memory. Please consult documentation from your MCU vendor, or documentation from ARM, for additional information. Thumb instructions are each 16 bits long, and have a corresponding 32-bit ARM instruction that has the same effect on the processor model . Thumb instructions operate with the standard ARM register configuration, allowing excellent interoperability between ARM and Thumb states.
What is difference between Thumb and Thumb-2 instruction set? Thumb-2 is an enhancement to the 16-bit Thumb instruction set . It adds 32-bit instructions that can be freely intermixed with 16-bit instructions in a program. The additional 32-bit instructions enable Thumb-2 to cover the functionality of the ARM instruction set.
Load bits 0-. 15 of Rd from the resulting address, and set bits 16-31 of Rd to bit 15. S. H. THUMB assembler. ARM equivalent. Action. Table 5-9: Summary of
