How to get correct reference to the content of the external address?

Latest Updated:04/02/2015


I am using High-performance Embedded Workshop with the E1 (or E20) to debug projects for RX-family MCUs. However, I am not able to get a correct reference to the contents of the external address space in the memory window.


In reference to an external address space, the operating mode of the microcontroller must be set for the connection of a debugging tool.
Set [Register Setting] as [On-chip ROM enabled extended mode] or [On-chip ROM disabled extended mode] in the [Operating Mode] category in the [Startup and Communication] tabbed page of the [Initial Settings] dialog box.
For correct access to the external address space, set the bus controller of the MCU so that the external address space is accessible.
