Use a EMIO to control a logic port of PL side from PS side

I need control a module's input port from PS side. I think Zynq's EMIO may do this. But all the usage of others is to map this pin to a physical pin routed to outside. So, can I use it to achieve my goal but without mapping it to a physical pin?

Hi diverger

To control the output of the PL part from the processor module, you can connect the module of Axi Peripheral to the GP port. To change or get the output state, you will need to write or read the register mapped to the processor module.

Yes, AXI_GPIO is a elegant method. I'm wondering if can use EMIO to control a port but without map this pin to any physical pin outside.
