您好，在例程中，SPI-STE引脚也是通过IO模式实现的。是否能实现SPI模块自动拉低或置高操作，谢谢。
?? ?：
We want that TI DSP to communicate with A3 MCU through SPI interface.However, it was found that the function of enabling pin STE to automatically set high and set low could not be realized through DSP configuration.The DEMO source provided by FAE is also implemented through IO port simulation.As shown in the figures below, SPI read/write enable signal STE is also realized through IO simulation.

你好，这与下帖似乎是同一个问题。关注一个帖子就好。
