9.27.6 Directives to control code generation

The directive .set insn32 makes the assembler only use 32-bit instruction encodings when generating code for the microMIPS processor. This directive inhibits the use of any 16-bit instructions from that point on in the assembly. The .set noinsn32 directive allows 16-bit instructions to be accepted.

Traditional MIPS assemblers do not support this directive.
