DM8168中未用管脚怎么处理?

Other Parts Discussed in Thread: MAX232

除了HDMI的相关管脚之外,其他的模拟视频输入输出管脚都没用,这些管脚怎么处理呢?直接不连线就OK吗?不用的RSV管脚也都不连线是吗?另外,UART的管脚只用收发两个管脚,然后连出到max232就行了是吧?

  • 你好,请参考datasheet的“3.2.1 Boot Configuration”未用到的管脚需要配置内部上拉或下拉电阻,或根据说明不连接。RSV管脚的处理在“3.2.22 Reserved Pins”节有说明。“另外,UART的管脚只用收发两个管脚,然后连出到max232就行了是吧?”是的。
