5 Setup the Debugger
5.3.1.2.3. Emulation memory allocation for an extended area
When memory extension or microprocessor mode is selected, emulation memory can be allocated to
the extended area to be debugged (in up to four areas).
Here, allocate memory for the debug target area and specify its mapping information.
Follow the procedure described below.
Bank
(Set bank address)
Specify the bank address of the debug target area to be allocated in
hexadecimal.
If specified as C0, C00000h is the start address of the debug target area.
Length
(Specify size of area)
Specify the size of the debug target area (256 bytes or 1 Mbytes).
If Length is specified to be "256 bytes," banks 00, 04, 08, and up to FC
(every four banks) are specified for Bank; if Length is specified to be "1
Mbytes," banks 00, 10, 20, and up to F0 (every 16 banks) are specified for
Bank.
Map
(Specify area map)
Specify the mapping information ("Internal" or "External") for the
specified area.
If no area is specified, select "No Use."
Internal The area specified to be "Internal" is mapped into the internal
area (emulation memory).
External The area specified to be "External" is mapped into the external
area (external resources in the target system).
• Areas for which "No Use" is selected for Map and those not specified here are mapped into
external areas.
If compared to the case where areas are explicitly specified to be "External," the only difference is
a download speed. (Downloading into these areas is slower than downloading into the areas
specified to be "External.")
• The internal ROM area is automatically mapped into the emulation memory. Therefore, there is
no need to set here.
• Be careful that the debug areas will not overlap.
• Make sure the total size of the specified debug target areas does not exceed the emulation
memory size of the emulation probe used.
The size of emulation memory that can be allocated varies with each emulation probe. (Consult
the user's manual of your emulation probe.)
