M3062PT2-EPB User’s Manual 3. Usage (How to Use the Emulator Debugger)
REJ10J0868-0200 Rev.2.00 January 16, 2006
3.1.2 MCU Setting Dialog Box
MCU setting dialog box sets the information of the user system. It will be displayed after closing the Init dialog box.
When the tab settings of 1 to 3 have been finished, click “OK”.
(1) MCU tab
1. MCU Setting
Specifying the processor mode
Select the appropriate processor mode that suits your
system.
Specifying the bus width
When specifying memory expansion mode or
microprocessor mode, select “16-bit” or “8-bit” for
“External Data Bus Width”.
Using or not using the memory space
expansion function
Specifies whether or not to use the memory space
expansion function when selecting memory expansion
mode or microprocessor mode. When using the memory
space expansion function, select “4MB Mode”. When
not, select “Normal Mode”
Using or not using the internal reserved
area expansion
Specifies whether or not to expand the internal reserved
area. Check the box if the internal reserved area
expansion bit (PM13) is “1”.
PM13=Set to 0:
Internal RAM area: 00400h--03FFFh
Internal ROM area: D0000h--FFFFFh
PM13=Set to 1:
Internal RAM area: 00400h--07FFFh
Internal ROM area: 80000h--FFFFFh
IMPORTANT
Notes on Selecting a Processor Mode:
When setting single-chip mode or memory expansion mode, the level of pin CNVSS of the MCU status should
be "L". The MCU status shows the pin level of the user system.
When setting microprocessor mode, the level of pin CNVSS of the MCU status should be "H".
When setting memory expansion mode or microprocessor mode, pins RDY# and HOLD# of the user system
should be "H".
When the user system is not connected, all modes are available.
Notes on Debugging the M16C/30P Group MCUs:
For debugging the M16C/30P Group MCUs, be sure to deselect the check box of the internal reserved area
expansion bit (PM13) before starting up the emulator debugger.
The M16C/62P Groups MCUs are used as an evaluation MCU for this product. An initial value of the internal
reserved area expansion bit (PM13) for the M16C/62P Group is different from that of for the M16C/30P Group.
(1) An initial value of the internal reserved area expansion bit (PM13) for the M16C/62P Group: 1
(2) An initial value of the internal reserved area expansion bit (PM13) for the M16C/30P Group: 0
When developing the program for the M16C/30P Group, be sure to set the initial value of the internal reserved
area expansion bit (PM13) to “0” in the program.
