DS90UB925QSEVB: DS90UB925/DS90UB948使用INTB引脚无法透传中断信号

  • 您好,INTB应该不可以透传。

    我想您可以 通过GPIO透传。将触摸屏的INT信号接948的GPIO信号,948的GPIO配置为input,925的GPIO配置为output。

    但是需要注意,和925搭配时候, 948必须配置围为18 bit mode, 才允许GPIO透传到925端。

    Note: if paired with a DS90UB925Q-Q1 serializer, the devices must be configured into 18-bit mode to allow usage of GPIO pins on the serializer。
