2.2.3 Clock settings on QB-78K0SKX1-DA side

(1) High-speed Ring-OSC operation

An 8 MHz clock supplied from the oscillator circuit on the QB-78K0SKX1-DA is used for high-speed Ring-OSC

emulation.

(2) Low-speed Ring-OSC operation

A 250 kHz clock supplied from the oscillator circuit on the QB-78K0SKX1-DA is used for low-speed Ring-OSC

emulation.

2.3 Target Device Selection

The target device is set by using SW2 on the QB-78K0SKX1-DA.

When emulating the 78K0S/KA1+ or 78K0S/KB1+: Set to KA1+/KB1+ side (3-6 pin side)

When emulating the 78K0S/KU1+ or 78K0S/KY1+: Set to KU1+/KY1+ side (1-4 pin side)

Figure 2-5. SW2 Setting

When using the 78K0S/KA1+ When using the 78K0S/KU1+

or 78K0S/KB1+ or 78K0S/KY1+

Caution Be sure to switch the power supply of the QB-78K0SKX1-DA off before changing the setting.

2.4 Software Settings

See the document ID78K0S-QB Operating Precautions supplied with the debugger (ID78K0S-QB) for details.

2.5 Connecting QB-78K0SKX1-DA to Target System

Connect the QB-78K0SKX1-DA to the target system using the target cable (supplied), etc.

CN1 of the QB-78K0SKX1-DA incorporates a male pin header, so be sure to mount a male pin header on the

target system connector. Connect corresponding pins to each other using a target cable with female connectors on

each end.

• Specifications of target cable (single-wire cables)

Red: 250 mm cable for power supply line (connected to VDD and AVREF pins) × 2

Black: 250 mm cable for GND line (connected to VSS and AVSS pins) × 2

Yellow: 250 mm cable for general signals × 26

• Specifications of target system pin header:

0.635 mm × 0.635 mm (height: 6 mm)

When mounting the pin header, ensure that the pin pitch is at least 2.54 mm.

CN1 of the QB-78K0SKX1-DA incorporates a 40-pin pin header, so by mounting an IDE connector on the target

system, the QB-78K0SKX1-DA can also be connected to the target system using a commercial IDE cable (ATA33

standard).

The pins in CN1 correspond functionally to the pins of the target device (pins 8, 16, 20, and 30). The functions of

the target device pins can be switched using the target device selection switch (SW2). The attached document QB-

78K0SKX1-DA Pin Header (CN1) Covers that indicates the signal name of the target device pins is provided. Use

the appropriate cover by cutting it off from the document along the lines with scissors or a cutter, and cover the CN1

on the QB-78K0SKX1-DA with it.

Cautions 1. Be careful not to hurt yourself with scissors or a cutter when cutting off the QB-78K0SKX1-

DA pin header (CN1) covers.

2. When emulating other than the 78K0S/KB1+, do not connect target I/F (pin header) pins that

have not been assigned pin functions (unused pins) to anything.

(5) Applying power

The procedure for applying power is described below using the case where a target system is connected as an

example.

When the USB interface cable is connected to the host machine, only the QB-78K0MINI’s POWER LED is ON

(the QB-78K0SMINI’s power is ON, the QB-78K0SKX1-DA’s power is OFF, and the target system’s power is

OFF).

When turning on the power with the QB-78K0SKX1-DA connected via the AC adapter, the QB-

78K0SKX1-DA’s POWER LED is ON and when applying power to the target system, the QB-78K0SKX1-

DA’s POC is OFF (the QB-78K0SMINI’s power is ON, the QB-78K0SKX1-DA’s power is ON, and the

target system’s power is ON).

After making sure the power is supplied to the QB-78K0SMINI, QB-78K0SKX1-DA, and the target system,

start up the ID78K0S-QB.

When the target system is not connected, select the “Not Permit” on the Target Power Off setting on the

ID78K0S-QB configuration dialog box.

CHAPTER 4 RESTRICTIONS

The following restrictions apply to the QB-78K0SKX1MINI.

{ Clock oscillation or clock input via a resonator on the target system is not supported. The clock differs between

the device and the tool (QB-78K0SKX1MINI) according to the option byte (OSCSEL1, OSCSEL0) setting as

follows.

OSCSEL1 OSCSEL0 Device Tool

0 0 Crystal/ceramic oscillation clock Clock on QB-78K0SMINI

0 1 External clock input Clock on QB-78K0SMINI

1 x High-speed Ring-OSC clock High-speed Ring-OSC clock

{ The low-speed Ring-OSC clock emulates at 250 kHz.

{ The QB-78K0SKX1MINI has 256 KB of RAM. However, the 256 KB RAM area can be accessed normally from

the user program even when a 128 KB device is being emulated, so be aware that problems such as stack

overflow may occur without your knowledge.

{ The characteristics of the AD converter, LVI, and ports are not fully equivalent to those of the device.

Pull-down resistors have also been inserted at the port signals to protect the target I/F. See APPENDIX A

TARGET INTERFACE EQUIVALENT CIRCUIT for details.

{ AVSS and VSS are equivalent on the QB-78K0SKX1MINI.

{ When using the QB-78K0SKX1MINI, a correct AD conversion result can be obtained even without waiting for 1

s to elapse after setting bit 0 (ADCE) of the A/D converter mode register (ADM) to 1. When using the actual

device, however, be sure to execute processing such as reading and discarding this result.

{ The internal functions (registers, peripheral macro, multiplier, etc.) of the QB-78K0SKX1-DA always operate for

the 78K0S/KB1+. Therefore, while the emulation is performed for 78K0S/KA1+, KU1+, or KY1+, if the bit of the

access to the bit is disabled under normal conditions. The multiplication instruction execution is enabled while

the emulation is performed for 78K0S/KA1+, KU1+, and KY1+.

User’s Manual U17272EJ1V0UM

APPENDIX A TARGET INTERFACE EQUIVALENT CIRCUIT

This chapter explains the differences between the signal lines of the target interface circuit of the QB-

78K0SKX1MINI and the signal lines of the target device.

Although the target device is a CMOS circuit, the target interface circuit of the QB-78K0SKX1MINI consists of an

emulation circuit that depends on the emulation CPU, TTL, CMOS-IC, etc.

When the target system is debugged by connecting it to the QB-78K0SKX1MINI, the QB-78K0SKX1MINI emulates

just as if the actual target device were operating on the target system.

However, small differences arise because the QB-78K0SKX1MINI actually is emulating.

The target interface equivalent circuit of the QB-78K0SKX1MINI is shown in Figure A-1 below.
