4. Usage (Emulator Debugger)
The required operating environmental is described below.
- Integrated development environment: High-performance
Embedded
Workshop
- Emulator debugger:
M16C R8C Compact emulator debugger Ver.1.01 Release 00 or later
Set the emulation memory in the MCU setting dialog box of the emulator debugger.
(1) MCU tab
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
Specifying the PM10 (bit 0 of the
address 0005h)
When using the CS2 Area Switch Bit (PM10) as
“
1
”
, check this box. Specify the processor mode
according to the user system.
IMPORTANT
Notes on Selecting a Processor Mode:
z
When setting 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.
z
When setting microprocessor mode, the level of pin CNVSS of the MCU status should be "H".
z
When setting memory expansion mode or microprocessor mode, pins RDY* and HOLD* of the user system should
be "H".
(2) MAP tab
Specifying the emulation memory
allocation
Sets the memory area assigned to the emulation
memory by 4KB. Up to four areas can be set.
An area set to [INTERNAL] will be allocated to
the emulation memory. An unchecked area or an
unset area will be allocated to external area.
The MAP setting is effective only in the CS3*,
CS2*, CS1* and CS0*. The maps of SFR,
internal ROM and RAM are set automatically.
* MAP tab is displayed only when connecting the emulation memory board.
