RM48L530: if I set a input GIO port to both open-drain and pull-up mode, what will happen?

Part Number: RM48L530

 I have three questions about GIO port set:

1: GIO input mode : opendrain + pullup/pulldown, what will happen? Will pullup/pulldown effect the input data?

2: GIO input mode : set the OUTPUT register, what will happen ?Will the output data effect the input data and the output data?

3: GIO output mode : opendrain + pullup/pulldown, what will happen?Will pullup/pulldown effect the input data?

  • 你好,不太理解您的问题,您的设置似乎完全是两个方向,您为什么要这么做?

    1.opendrain应该只适用于output mode。

    2.既然是input mode 为什么要置位output?

    3.既然是output mode 还会有input data?
