2.12 Optional SODIMM Memory Selection
Optional SODIMM memory is used when user wants to access external memory area when the target
system is not available.
If SODIMM is purchased, user has to open the casing and fix the SODIMM in the correct socket (Please
refer to the SODIMM user manual).
In order to use the SODIMM, user has to enable the memory at the desired address:
•
In the Memory mapping dialog, click on Add .
•
Key in the desired address at From at To .
•
Select the attribute i.e., Emulator read-write, Emulator read only or Emulator Guarded.
NOTE: 2Mbytes (Four banks of 512 Kbytes) of Optional Memory (purchase separately) can be used in
the CE2000-H8S/2238 emulator. User can map the memory (minimum of 32 Bytes to a maximum of
2MBytes) to any space except internal space (e.g. internal ROM, RAM, peripherals, …). If the target
memory is present in the same area as the optional memory, the optional memory will have a higher
priority to be accessed.
e.g.
If user maps the address from H’20000 to H’80002 as Emulator-Read-Write, HEW will allocate 2
banks of memory for the user, to access from area H’20000 to H’8001F.
