产生中断的功能模块将中断信号通过中断屏蔽控制单元分别输入到中断向量存储单元和控制输出单元；
The function module to generate the interval input the interval signal into interval vector memory unit and output control unit through interval shield control unit.
当将控制转移到合适的段时，处理器清除IF标志，因此关闭将来的可屏蔽中断。
While transferring control to the proper segment, the processor clears the IF flag, thus disabling further maskable interrupts.
文中并给出一些抗干扰、利用不可屏蔽中断等问题的方法。
Several methods for solving the problems of anti-interference, non-maskable interruption, etc. are also presented.
