General Precautions for Handling This Product
1. Circumstances not covered by product guarantee
• If the product was disassembled, altered, or repaired by the customer
• If it was dropped, broken, or given another strong shock
• Use at overvoltage, use outside guaranteed temperature range, storing outside guaranteed temperature range
• If power was turned on while connection to the AC adapter, USB interface cable, or target system was in an
unsatisfactory state
• If the cable of the AC adapter, the USB interface cable, the emulation probe, or the like was bent or pulled excessively
• If an AC adapter other than the supplied product was used
• If the product got wet
• If this product is connected to the target system when there is a potential difference between the GND of this product
and GND of the target system.
• If the connectors or cables are plugged/unplugged while this product is in the power-on state.
• If excessive load is applied to the connectors or sockets (As for handling, please see 2.3 Mounting and Connecting
Connectors).
• If a metal part of the power switch, cooling fan, or another such part comes in contact with an electrostatic charge.
• If the product is used or stored in an environment where an electrostatic or electrical noise is likely to occur.
2. Safety precautions
• If used for a long time, the product may become hot (50°C to 60°C). Be careful of low temperature burns and other
dangers due to the product becoming hot.
• Be careful of electrical shock. There is a danger of electrical shock if the product is used as described above in 1.

QB-78K0FX2LIn-CircuitEmulator CHAPTER2 SETUPPROCEDURE
R20UT2057EJ0100 Rev.1.00 Page 19 of 37
2012.05.18
2.1 Software Settings
Check the user's manual for the debugger that will be used.
2.2 Clock Settings
The IECUBE clock must be set to the clock used by the target device. For details about how to set the clock, check the
user's manual for the debugger that will be used.
IECUBE clock settings for the clock used by the target device are shown below.
Oscillation with the resonator on the target system is not supported. Therefore, the in-circuit emulator cannot emulate
the oscillation operation of the clock on the target system.
Table 2-1. List of clock settings
Clock Used Clock Supply
(a) When the clock generated within the emulator is used
(b) When the clock (a square wave) is supplied from the target system
(1) High-speed system clock
(X1 oscillator or External input)
(c) When the oscillator (OSC1) mounted onto the emulator is used
(2) Internal high-speed
oscillation clock
Uses the clock internally generated from the emulator
(3) Internal low-speed
oscillation clock
Uses the clock internally generated from the emulator

(1) High-speed system clock
The clock settings are listed below.
Table 2-2. Settings for High-Speed System Clock
Type of Clock to Be Used OSC1
(a) When the clock generated within the emulator is used –
(b) When the clock (a square wave) is supplied from the target systemNote –
(c) When the oscillator (OSC1) mounted onto the emulator is used Oscillator mounted
Note This setting is not possible when TARGET LED is not lit.
Remarks 1. Settings other than the above are prohibited.
2. Selection of (a) or (b) is possible regardless of whether the oscillator is not mounted in the
OSC1socket.
(a) When the clock generated within the emulator is used
This method uses the clock generated inside the emulator.
The oscillation frequency that will be used must be set in the debugger. For details about how to set the
oscillation frequency, check the user's manual for the debugger that will be used.
(b) When the clock (a square wave) is supplied from the target system
The clock input from the target system is then used.
To input a clock from the target system, input to the clock pin (X2) the square-wave signal with the same
voltage potential as that of the target device supply voltage (VDD). Inputting the inverted signal to X1 is not
necessary.
The selectable frequencies are same as those of the target device.
For debugger settings, check the user's manual for the debugger that will be used. Oscillation by a resonator
in the target system is not supported.
(c) When the oscillator (OSC1) mounted onto the emulator is used
Mount an oscillator in the OSC1 socket in the emulator and then select the “Clock socket” in the debugger.
The clock generated from the oscillator mounted on the emulator is used.
The selectable frequencies are same as those of the target device.
To modify the clock setting, the acrylic board on the bottom of the QB-78K0FX2L must be removed.
The acrylic board can be removed by lifting it up.
For debugger settings, check the user's manual for the debugger that will be used.
