  • Page 19: Software Settings

    QB-RL78G1A In-Circuit Emulator CHAPTER 2 SETUP PROCEDURE 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.
  • Page 20 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-RL78G1A must be removed. The acrylic board can be removed by lifting it up.
  • Page 21 QB-RL78G1A In-Circuit Emulator CHAPTER 2 SETUP PROCEDURE Figure 2-1. Acrylic Board Removal Method Note As an oscillator to be mounted in the OSC1 socket in the emulator, use the one that satisfies the following specifications. - Supply voltage: 5.0 V - Output level: CMOS Note An oscillation circuit that uses a resonator cannot be used.

  • Page 30: Connecting Qb-Rl78G1A To Target System

    There are three GND wires in the emulation probe. Connect them to the QB-RL78G1A and target system. <1> Fasten the GND wire on the QB-RL78G1A side of the emulation probe to the nut on the bottom of the QB-RL78G1A using a #0 or #1 Phillips precision screwdriver (connection of B to A in Figure 2-8).
  • Page 31 <2> Be sure to connect the GND wire of the emulation probe to the QB-RL78G1A and the target system. If it cannot be connected, the impedance of the cable is unstable and could bring about lowering of signal transmission characteristics or distortion of the output waveform for an input waveform.
