DS90UB926Q-Q1: 926和925使用INTB的问题

Part Number: DS90UB926Q-Q1

有个车机显示屏项目,触摸信号走I2C连接到925,中断引脚接INTB;925和926作为一对使用,MCU连接I2C和INBT_IN,请问926手册中8.3.19 Interrupt Pin - Functional Description and Usage (INTB)的描述是否是说中断信号通过926的INBT_IN引脚传输到925,需要通过读寄存器清除中断状态,释放INBT引脚呢?

如果是我的接法,是否需要不停读取925的ISR寄存器获取中断状态才能让926的INBT_IN引脚拉低还是释放?
