(2) Selecting a mode
Select one of the following modes for assigning emulation memory to the internal ROM.
- Do not allocate emulation memory
- Use emulation memory
- Automatically allocate IEMEMx when writing to a software break occurs.
[Do not allocate emulation memory]:
The emulator will not use emulation memory allocated as internal ROM.
[Use emulation memory]:
The emulator will use emulation memory allocated as internal ROM.
[Automatically allocate IEMEMx when writing to a software break occurs]:
Emulation memory will automatically be allocated as internal ROM when an attempt is made to set a software break at a
location in the internal ROM area. If you have manually assigned IEMEM0 and IEMEM1 as emulation memory to internal
flash ROM, however, automatic assignment of emulation memory will not be performed.
Even when emulation memory has been allocated automatically, the allocated memory is treated as if it had been manually
allocated: deleting a software breakpoint does not release the corresponding memory.
(3) Write the contents of the flash ROM areas to IEMEMx
Selecting a checkbox makes the assignment of emulation memory to internal ROM areas include writing the contents of the
internal flash-ROM area to the corresponding emulation memory block. If a program is downloaded to internal ROM, the
program will also be downloaded into the emulation memory block.
(4) Assign emulation memory to external space
Up to four blocks of emulation memory can be allocated to external space. Select the checkboxes for the areas you wish to use
and specify the addresses where they start and end. Note that the 20 lower-order bits of the addresses are fixed because the
blocks are only specifiable in 1-Mbyte units. Assignment of emulation memory to an external space is only possible at the time
the emulator is booted-up.
