Forum Post: RE: assemblerprogramming for Launchpad with IAR workbench/ Problems with the call function

Maybe from my debugging example you can understand stack behaviour...

        mov.w #WDTPW + WDTHOLD, &WDTCTL
        mov.w #00280h, SP

        call #DbgStr
        db 'Device ', 0
        mov.w &00FF0h, R15
        call #DbgWordHex
        call #DbgCR
        call #DbgRegs
        call #DbgCR
        call #DbgSR
        call #DbgCR
        push.w #01234h
        push.w #05678h
        push.w #0ABCDh
        call #DbgStack
        call #DbgCR
        pop.w R15
        pop.w R15
        pop.w R15
