IMPORTANT
Notes on Target System:
• Pin Vcc of the emulator is connected to the target system to observe the voltage of the target system.
Therefore design your system so that the emulator MCU is powered by the target system.
• The voltage of the target system should be within the following.
(1) When JP1 is set as VCC1 = 2:
3.0 V ≤ VCC1 = VCC2 ≤ 5.5 V
(2) When JP1 is set as VCC1 > 2:
4.8 V ≤ VCC1 ≤ 5.2 V
3.3 V ≤ VCC2 < VCC1
Do not change the voltage of the target system after turning on the power.
Note on NMI* Interrupt:
• NMI* input from the target system is accepted only while a user program is being executed (only
while the RUN status LED on the PC7501's upper panel is lit).
Note on RESET* Input:
• The RESET* input from the target system is accepted only while a user program is being executed
(only while the RUN status LED on the PC7501's upper panel is lit).
Note on RDY* Input:
• Be sure to input "L" to pin RDY* of the target system during the user program executing (only while
the RUN status LED on the PC7501's upper panel is lit). Inputting "L" to pin RDY* during the user
program stopping may cause a malfunction of the emulator.
Note on HOLD* Input:
• Be sure to input "L" to pin HOLD* of the target system during the user program executing (only
while the RUN status LED on the PC7501's upper panel is lit). Inputting "L" to pin HOLD* during
the user program stopping may cause a malfunction of the emulator.
Notes on Using This Product When the Voltage of VCC1 is Higher than That of VCC2:
• If using this product when the voltage of VCC1 is higher than that of VCC2, set the JP1 to VCC1>2.
For the switch JP1, refer to "3.5 Setting Switches" (page 31).
•When the JP1 is set to VCC1>2, the voltage of VCC2 on the target system should be 3.3 V or more.
• If using a CPU clock of 30 MHz or more when the voltage of VCC1 is higher than that of VCC2,
set the SFR area of the intelligent I/O function to 2-wait (set the PM13 bit to "1") when reading this
area. This precaution only needs to be observed when using an emulator, and does not apply for
the actual MCU.
