STM32N657X0

Hello,developers.I have a question about the usage for a signal in the  STM32N657X0.The E2 pin in the VFBGA264 package,PWR_ON,is defined as an input in the pin definition table ,but it can also be used as an output enanle   signai in the logic diagram.What exactly should this signal PWR_ON be used for?

各位开发者你们好,我在使用STM32N657X0时,对里面的一个信号使用有疑问。

VFBGA264封装的E2管脚,也就是PWR_ON这个信号,在管脚定义表里面为输入Input,但是在逻辑图中又写的是作为输出使能用的信号。

这个信号到底是输出还是输入呢?PWR_ON这个信号到底怎么处理呢?
