IMPORTANT
Note on Clock Supply to the MCU:
A clock supplied to the evaluation MCU is selected by the Clock tab in the Init dialog box of the
emulator debugger.
(1) When Internal is selected:
A clock generated by the oscillation circuit in the emulation pod is supplied to the evaluation MCU.
The clock is continually supplied to the evaluation MCU regardless of "user system clock status"
and "user program execution status"
(2) When External is selected:
Clock supply to the evaluation MCU depends on oscillation status (oscillate/off) of the user system.
Notes on Setting the Work Area When Starting Up the Emulator Debugger:
With this product, the emulator uses 54 bytes as a work area in emulation memory. In single-chip
mode, set the work area address at 10000h. In memory expansion or microprocessor mode, set the work
area address in an area other than SFR area (00000h--003FFh), external area of multiplex bus setting,
reserved area of 27000h--27FFFh and stack area used by the emulator for reset command execution
(0FFF9h--0FFFFh). For more details, see "3.1.2 Setting the Work Area" (page 36).
The top address of the work area should be an even-numbered address.
Set the work area as MAP=INT.
For example, if the work area is set at 10000h, the emulator uses 54 byte area of 10000h to 10036h.
Notes on Stack Area:
With this product, a maximum 7 bytes of the user stack is consumed. Therefore, ensure the +7 bytes
maximum capacity used by the user program as the user stack area. If the user stack does not have
enough area, do not use areas which cannot be used as stack (SFR area, RAM area which stores data, or
ROM area) as a work area. Using areas like this is a cause of user program crashes and destabilized
emulator control.
