使用的是AM3354 ZCZ产品,查看资料的19页,AIN0-AIN4虽然TYPE类型都是A(Analog),但是A后面有标注,点击标注可以看到48页的注解如下:
This terminal is analog input that may also be configured as an open-drain output 。
这是否表明该端口是模拟输入同时也能配置为开漏输出。但是软件人员告知我软件界面没有配置为输出的选项。所以这几个引脚到底能不能配置为输出啊?

AIN[0] can be configured to operate as open-source.
AIN[2:1] can be configured to operate as open-source or open-drain.
AIN[4:3] can be configured to operate as open-drain.
具体可以看一下这个帖子里面的描述。
