sir, 

__bis_SR_register(LPM3_bits);          

AND

__bis_SR_register(LPM3_bits | GIE);

What is difference in these two statements,

 __bic_SR_register_on_exit(LPM3_bits | GIE);

when i come out from lpm3 mode by above statement my rtc interrupt is going to stop

    this sets the register bit for LPM3,

    this sets the register bit for LPM3 and enable the general interrupts.

    Your above statement clears the register bits for LPM3 and the general interrupt, so it actually disables the general interrupt.

    What you wanted to do is actually set the bits I assume. In the above statement replace "bic" with "bis" so setting the bits. 

    Please correct me if I've misunderstood what you want to do though.

    Best regards,
