堆栈指针设置正确但致电不工作

我正在为MSP430F1232使用Ti Code Composer Studio。从汇编器中的模板开始，对例程的调用行不通，但是当我将例程直接放入代码中时，它可以正常工作。为什么电话不起作用？

;generated code, the watchdog is stopped and the stack pointer is set correctly
RESET       mov.w   #__STACK_END,SP         ; Initialize stackpointer
StopWDT     mov.w   #WDTPW|WDTHOLD,&WDTCTL  ; Stop watchdog timer
;-------------------------------------------------------------------------------
; Main loop here
;-------------------------------------------------------------------------------
            mov.b   #0FFh,P1DIR
            mov.b   #0,P1OUT
$1
            call    delay

            xor.b   #001h,P1OUT
            jmp     $1

            .newblock ;reuse local labels
delay       push    r14
            mov     #1000,r14
$1
            dec     r14
            jne     $1
            pop     r14
            ret

原文

I'm using TI Code Composer Studio for the MSP430F1232.
Starting from a template in assembler, a call to a routine doesn't work but when I put the routine directly in the code,it works. Why does the call won't work?

;generated code, the watchdog is stopped and the stack pointer is set correctly
RESET       mov.w   #__STACK_END,SP         ; Initialize stackpointer
StopWDT     mov.w   #WDTPW|WDTHOLD,&WDTCTL  ; Stop watchdog timer
;-------------------------------------------------------------------------------
; Main loop here
;-------------------------------------------------------------------------------
            mov.b   #0FFh,P1DIR
            mov.b   #0,P1OUT
$1
            call    delay

            xor.b   #001h,P1OUT
            jmp     $1

            .newblock ;reuse local labels
delay       push    r14
            mov     #1000,r14
$1
            dec     r14
            jne     $1
            pop     r14
            ret

我用类似的微型（MSP430FR2433）重现了问题。
事实证明，寻址模式是错误的。
对于其他微处理器类型，我们用于

call MySubroutine
...
MySubroutine:

MSP430，我们应该使用

call #MySubroutine
...
MySubroutine

I reproduced the problem with a similar micro (MSP430FR2433).
It turned out that the addressing mode was wrong.
With other microprocessor types, we use
