IMPORTANT
Note on Clock Supply to the MCU:
• Clock can be supplied to the evaluation MCU in one of the following two ways. This is determined
by emulator debugger clock selection.
(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 "target 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 target
system.
Note on RDY* Input:
• Be sure to input "L" to pin RDY* of the target system during the user program execution (only while
the RUN status LED on the PC4701's front panel is lit). Inputting "L" to pin RDY* during the user
program stopping may cause a malfunction of the emulator.
Notes on HOLD* Input:
• Be sure to input HOLD* of the target system during user program execution (only while the RUN
status LED on the PC4701's front panel is lit). If "L" is input to pin HOLD*, the emulator will not
work normally.
• When inputting "L" to pin HOLD* to run into the HOLD state, P00 to P52 will be in the HOLD
state delaying by 2.5 cycles than the actual MCU (see Table 5.5 and Figure 5.4).
Note on NMI* Input:
• "L" input from the target system to pin NMI* is accepted only while a user program is being
executed (only while the RUN status LED on the PC4701's front panel is lit).
Note on RESET* Input:
• "L" input from the target system to pin RESET* is accepted only while a user program is being
executed (only while the RUN status LED on the PC4701's front panel is lit).
Notes on Setting the Work Area When Starting Up the Emulator Debugger:
•With this product, the emulator uses 32 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 (0000h--003FFh), external area of multiplex bus
setting and stack area used by the emulator for reset command execution (0FFF9h--0FFFFh). For
more details, see "2.4 (2) Setting the Work Area" (page 25).
• 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 02C00h, the emulator uses 32-byte area of 02C00h to 02C1Fh.
