DSP28x_usDelay(Uint32 Count)关于参数传递问题

使用时申明extern void DSP28x_usDelay(Uint32 Count);

我看了下汇编DSP2803x_usDelay.asm代码如下:

       .def _DSP28x_usDelay
       .sect "ramfuncs"

        .global  __DSP28x_usDelay
_DSP28x_usDelay:
        SUB    ACC,#1
        BF     _DSP28x_usDelay,GEQ    ;; Loop if ACC >= 0
        LRETR

我想问下,使用时DSP28x_usDelay(Uint32 Count)里面的参数是怎么传递进去的?
