如果串行接口是无法产生一个中断，将此值设置为任何未使用的中断向量地址。

If the serial interface is not able to generate an interrupt, set this value to any unused interrupt vector address.

我的理解是中断向量仍然是0x0，只是通过一种转换将这个向量表又复制到0x33ffff00地址了。

My understanding is interrupted vector is still 0 x0, only through a change to the scale of this is to copy the addresses 0 x33ffff00.
