    Akila,

    I believe you need an .s43 file to use assembly with IAR. The following app note may help: www.ti.com/lit/slaa140

    I would check with IAR support however to get a full answer to your inquiry.

    Regards,
    JH

    Those are not msp430 opcodes, so it will never work.

    Thanks Tony.

    Then what is the opcodes for msp430. do we have any list or document related to asm opcodes?

     

    Thanks,

    Akila.

The others are emulated by using #0 as source for example.
