As we know, ADuC84x can expand up to 16Bbyte XRAM by 24bit addressing. Can we
use Keil to debug the system when using external RAM? If yes, how do we
debug/observe the external data in Keil?

 

Yes, keil can debug the full external SRAM memory.
We don’t have an evaluation board with external SRAMs on it but, it will work
if Port0/Port2/ALE/RD/WR pins are connected to external memory.
You just need to populate the target memory menu that you highlighted and set
up the external memory SFRs in user code.
When debugging, just open the memory window and scroll to the appropriate
address.
