Reading the status of port pin in CY8C9560A

[Anonymous]

I need to obtain the status of a port pin of CY8C9560A after sending a value. Can I get the status by reconfiguring the same port as input and reading it?

If you meant that at one moment you want to configure a pin as an output and after some time as an input then yes you can do that.

Let me elaborate.

   

For example, suppose port A is configured as output port and the value 32H is sent. Now it is reconfigured as input port and read. Would I get back the value 32H?

In the datasheet attached, it says in page 3 that, "

It is significant for me because I have to include a status check of the port in my project.

When the Input register is read, the external pin logic levels are captured and transferred".
