This has undesired effects on some GIC registers, for eg GICC_IAR register can only read once to acknowledge the interrupt.

这不希望一些GIC寄存器效果，如GICC_IAR寄存器只能读一次承认中断。

The analysis and experiments shows that an interrupt must take place during the halt acknowledge cycle of the CPU.

分析与实验结果表明，中断必须发生在CPU的暂停响应阶段。
