Hi,
As per topic I need to add ADC with QSPI interface to the project that already has QSPI NOR-Flash. They can be multiplexed by CS pins. Why configurator is letting to connect only 1 QSPI to the same pins and how to overcome it?

Hello @MuKh_4408861 ,

You should be able to multiplex the two components but not at design time. You must do it at runtime programmatically. You cannot multiplex the two components in the TopDesign to use the same pins because the PSoC Creator internally won't know which functionality to assign to the pins. 

You need to add one component in TopDesign and write the configuration structures manually for the other component. Whenever you want to switch between the components, change the functionality of the pins and then initialize your other component. And then vice versa to switch to the first component. I think it should work.

Let me know your observations.

Regards,
Dheeraj
