为什么我的emac通信主程序中加了中断地址入口的程序就运行不了了？IRQ_setVecs(vectors);  //Sets the base address of the interrupt vectors  我在主函数main()中添加的一句话，哪位高手给指点一下？
以下是ves_dm642.asm的程序，我没有动：

* Assembly file to set up interrupt service table (IST)

   .ref _c_int00

*------------------------------------------------------------------------------
* This is a macro that instantiates one entry in the interrupt service table.
*------------------------------------------------------------------------------
VEC_ENTRY .macro addr
    STW   B0,*--B15
    MVKL  addr,B0
    MVKH  addr,B0

* This is a dummy interrupt service routine used to initialize the IST.
*------------------------------------------------------------------------------
_vec_dummy:
  B    B3
  NOP  5

*------------------------------------------------------------------------------
* This is the actual interrupt service table (IST). It is properly aligned and
* is located in the subsection .text:vecs. This means if you don't explicitly
* specify this section in your linker command file, it will default and link
* into the .text section. Remember to set the ISTP register to point to this
* table.

.sect ".text:vecs"
.align 1024

_vectors:
_vector0:   VEC_ENTRY _c_int00    ;RESET
