Cpu And I/O Registers Access - Renesas CE2000-H8S Series User Manual

www.DataSheet4U.com
At startup, when user select the Device, Package and Mode in the Configure Platform dialog, default
mapping for the application will be generated. This can be viewed under Memory Mapping dialog. In
default, if the device has an external address space, it will be set to be external guarded. Upon connecting
the emulator to a target system or accessing the optional SODIMM, user has to change this default
setting i.e.,
To access external target memory
•
Set External Guarded to External Read Write or External Read Only
To access optional SODIMM memory
•
Set External Guarded to Emulator Read Write or Emulator Read Only
For the On Chip attributes, user can only change the attributes from Read-Write and Write to Guarded,
but not at any other possibilities. In the case for the Emulator and External attributes, user can set it to any
combination.

3.13 CPU and I/O Registers Access

User can access these registers directly through the Register and I/O windows respectively during break
mode only.
