CHAPTER 2 SETUP PROCEDURE CHAPTER 2 SETUP PROCEDURE This chapter explains the QB-RL78L12 setup procedure. Setup can be completed by performing installation setup in the order in which it appears in this chapter. Perform setup along the lines of the following procedure.
QB-RL78L12 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-RL78L12 must be removed. The acrylic board can be removed by lifting it up.
Page 21
QB-RL78L12 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 oscillator that uses a resonator cannot be used.
Page 22
QB-RL78L12 In-Circuit Emulator CHAPTER 2 SETUP PROCEDURE Figure 2-3. Mapping of Oscillator to Socket Remark Insert the oscillator into the socket, take care for the pin 1 position. (2) Internal high-speed oscillation clock This method uses the clock inside the emulator by configuring the use of the high-speed oscillation clock in the user program.
CHAPTER 2 SETUP PROCEDURE 2.3 Mounting and Connecting Connectors (When Using S Type Socket) This section describes the methods of connecting the QB-RL78L12 and target system. Make connections with both the QB-RL78L12 and target system powered OFF. The following abbreviations are used in this section:...
QB-RL78L12 In-Circuit Emulator CHAPTER 2 SETUP PROCEDURE 2.3.2 Mating theTC to EA Mate the TC and EA by following the procedure below. (1) Check the orientation of pin 1, align the TC guide pin to the guide hole at the tip of the EA flexible printed circuit (FPC), and then insert it.
QB-RL78L12 In-Circuit Emulator CHAPTER 2 SETUP PROCEDURE 2.3.3 General Precautions when Using the EA, TC (1) Causes of connector conductivity problems (a) When flux gets inside the connector when mounting the TC Since flux easily rises into the connector, if it gets into the connector, completely wash it out using a solvent such as alcohol.
CHAPTER 2 SETUP PROCEDURE 2.4 Mounting and Connecting Connectors (When Using T Type Socket) This section describes the methods of connecting the QB-RL78L12 and target system. Make connections with both the QB-RL78L12 and target system powered OFF. The following abbreviations are used in this section:...
QB-RL78L12 In-Circuit Emulator CHAPTER 2 SETUP PROCEDURE 2.4.2 Mounting YQ to NQ (1) After confirming that there are no broken or bent YQ contact pins, fit the YQ in the NQ and fasten it using the supplied YQGUIDE (for the fastening method, see the next step, (2)). If repeatedly inserting and removing, be sure to inspect the YQ pins before fitting.
QB-RL78L12 In-Circuit Emulator CHAPTER 2 SETUP PROCEDURE 2.4.4 Precautions for handling NQ, YQ, SA, and CA (1) When taking the NQ from the box, press down on the body and take out the sponge first. (2) Since the pins of the YQ are thin and easily bent, be careful. When inserting it in the NQ, confirm that there are no bent pins.
QB-RL78L12 In-Circuit Emulator CHAPTER 2 SETUP PROCEDURE 2.4.5 Precautions for mounting IC using NQ and MA (1) Confirm that there is no weld flash in the resin (sealant part) of the IC. If there is weld flash, remove it using a knife or the like.
There are three GND wires in the emulation probe. Connect them to the QB-RL78L12 and target system. <1> Fasten the GND wire on the QB-RL78L12 side of the emulation probe to the nut on the bottom of the QB-RL78L12 using a #0 or #1 Phillips precision screwdriver (connection of B to A in Figure 2-8).
Page 31
QB-RL78L12 In-Circuit Emulator CHAPTER 2 SETUP PROCEDURE <3> Connect the exchange adapter and emulation probe to the target connector. <4> Connect the GND wires on the target system side of the emulation probe to the target system GND. If a pin or screw is fastened to the target system GND, remove the transparent terminal cover on the end of the GND wire and fasten the Y terminal of the GND wire to the target system (C in Figure 2-8).
<2> Be sure to connect the GND wire of the emulation probe to the QB-RL78L12 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.
2.7 Connecting USB Interface Cable and AC Adapter Plug the USB interface cable supplied with the QB-RL78L12 into the USB connector of the host machine, and plug the other side into the USB connector on the rear of the QB-RL78L12.
QB-RL78L12 In-Circuit Emulator CHAPTER 3 SETTINGS AT PRODUCT SHIPMENT CHAPTER 3 SETTINGS AT PRODUCT SHIPMENT Table 3-1. Settings at Shipment Item Setting Remarks Note Not mounted Oscillator can be mounted OSC1 Power switch Set to OFF at shipment. Note The oscillation circuit using an oscillation cannot be used.
When debugging is performed by connecting the QB-RL78L12 to the target system, the QB-RL78L12 emulates the target device as if it operates in the target system. However, the target device and the QB-RL78L12 operate differently in the following ways. Consequently, the target device should be used for final evaluation before launching mass production, and the customer is to be responsible for judging the appropriateness of applying the QB-RL78L12.
