The SEMC interface supports 4 types of devices, I would like to confirm the following questions:

1. Does it support access two different devices through the SEMC interface in the same project, such as an external SDRAM plug-in, an external SRAM, and data interaction with two peripherals is required in the same project.

2. If it is supported, how much delay is there when the two devices are switched?

thankyou!

Hi @jiaxin ,

1. Yes, 可以支持。他们的CS是不同的。数据线可能是复用的。

2. 这个很难讲。从一个cs起来到另一个落下大概需要3~4个clock。
