Hi, How to interface STM32H743ZI with 8080-MCU 18-bit parallel interface?

Same way you'd interface anything to anything else:

A complex system that works is invariably found to have evolved from a simple system that worked.
A complex system designed from scratch never works and cannot be patched up to make it work.

Hi Andrew,

Thanks for the information.

Kindly help me out in below query,

We have D/CX pin along with above pins in LCD. ((D/CX): This pin is used to select “Data or Command�? in the parallel interface).

Can we connect GPIO to D/CX pin, or do we have any dedicated pin in FSMC interface?

Per the link, you need to study the documentation to work that out.

You titled this thread, "8080-MCU" - did you really mean that? Looks like you're talking about an LCD - not an MCU?
