3.10 Memory Functions
General functions such as fill, copy, search, save and load memory are supported, by means of clicking
the mouse button. Modification of memory can be made via byte, word, or long word access.
NOTE: User has to set the bus state controller correctly before the external memory can be accessed.
These functions can be applied on all the three memory type of the emulator, namely:
•
On-Chip Memory (internal ROM/RAM)
•
Optional SODIMM Memory (2Mbytes SRAM)
•
User Target Memory
3.11 Parallel-On-The-Fly (POTF)
POTF feature can be observed in the Monitor window in HEW.
3.12 Memory Mapping
This functions as a traffic controller to direct the MCU to access the intended area of memory. In general,
there are three types of memory area, namely:
•
On Chip Memory
•
Optional Emulator Memory
•
External Target Memory
Two more constraints are set to prevent user's program from running wild. i.e.
•
Write–protect
•
Access-inhibit or Guarded
These protections can be allocated to the memory area in minimum unit of 32 bytes resolution.
These constitute nine possible attributes setting:
•
On Chip Read Write
•
On Chip Read Only
•
On Chip Guarded
•
Emulator Read Write
•
Emulator Read Only
•
Emulator Guarded
•
External Read Write
•
External Read Only
•
External Guarded
To change the setting, user has to:
•
Click on the Add button in Memory Mapping dialog.
•
Key in the desired address at "From and To". &
•
Select the attribute.
