(3) Setting Emulation Memory
This product has two kinds of emulation memory and how to allocate is different depending on which
processor mode is selected. Table 4.2 shows how to set the emulation memory for each processor
mode.

(4) Emulation Memory Allocation as Expansion Area
This section explains about setting emulation memory for expansion purposes in memory expansion
mode and microprocessor mode. To use emulation memory as expansion area, set memory allocation
as indicated here below. Emulation memory specifications are given in Table 4.3.
(1) Setting bank address (Bank): Specify the bank address of the area to be allocated for expansion
as a hexadecimal number.
For example, specifying "C0" allocates the bank from address C00000h.
When 256 KB is specified as the Length, bank addresses can be specified from 00, 04, 08 up to
FC in 256KB blocks.
When 1 MB is specified as the Length, bank addresses can be specified from 00, 10, 20 up to F0
in 1MB blocks.
(2) Specifying area size (Length): Specify the size of the specified expansion area. The area from
the specified address to the size specified here is allocated as
external area and internal area. Length can be specified as 256
KB or 1 MB.
(3) Specifying area map (Map): Select whether the specified area is to be allocated as internal
area (used as emulation memory) or external area (used by an
external device, etc.).
• When INTERNAL is specified: This bank is allocated as internal area and used for expan-
sion.
• When EXTERNAL is specified: This bank is allocated as external area and used by the target
system as an external resource.
• When No Use is specified: This bank is allocated as external area and used by the target
system as an external resource.
Areas not specified here are allocated as external area. The only difference from the area specified
as EXTERNAL area is download speed. Download to the area specified as EXTERNAL area is
faster than to the other unspecified areas.
