2. Outline  
The M38517T-ADS is a temporary target board used to develop software with a PC4701 emulator  
system. It supplies to the emulator MCU the minimum required signals needed to operate the  
emulator MCU, including power supply voltage, clock signals and reset signals. Use it when the  
target system is not ready.

4. Setting Up  
This chapter describes how to set up the M38517T-ADS.  
CAUTION  
Note on Setting Up:  
• Always shut OFF power before connecting this product. The power ON state could  
destroy internal circuits.  
4.1 Mounting an Emulator MCU  
Mount an emulator MCU on the M38517T-ADS. After checking the position of the No. 1 pin of the  
emulator MCU, mount the emulator MCU referencing Figure 4.1.

4.2 Connecting to the Emulation Pod  
(1) Insert the connector on the tip of the emulation pod probe to the socket on the emulator MCU.  
(2) Connect the cables of the M38000TL2-PSW2 as shown in Table 4.1 depending on the emulator  
MCU you use.  
Do not connect the Vcc cable (yellow) to pin Vcc (TP1).

(4) Connect a power supply (not included) to pin Vcc (TP1) of the M38517T-ADS. And connect the  
GND output of the power supply to pin Vss (TP2). Use the power supply whose rising time is 10  
ms or less.

4.3 Setting the Switches  
Set the switches SW1 to SW3 according to your applications. Table 4.3 describes the functions of  
the switches SW1 to SW3.

PORT  
Function  
SW1  
PORT/XCIN  
Allows you to choose whether to supply the sub-clock  
signals (32.768 kHz) to the MCU's XCIN pin (pin 16).  
To use pin P21/XCIN as an I/O port, choose the PORT  
side.  
To use the sub-clock signals, choose the XCIN side.  
SW2  
SW3  
VREF  
Vcc  
Vss  
Allows you to choose whether to apply Vcc or some  
other source to the MCU's VREF pin (pin 2). In the  
case of the latter, choose the J1-2 side, and apply a  
voltage within a prescribed range to the J1-2.  
CNVss  
Allows you to choose which to connect, Vcc or Vss, to  
the MCU's CNVss (pin 15).

5. Oscillator Circuit  
5.1 Oscillator Circuit Board  
The M38517T-ADS has a built-in oscillator circuit board on which a 4.0MHz oscillator is mounted.  
Figure 5.1 shows an external view of the OSC-2 oscillator circuit board (bare board) and where  
connector pins are located. Figure 5.2 shows the circuitry of the OSC-2 oscillator circuit board (bare  
board). Use the number of oscillator circuits recommended by the oscillator manufacturer.  
J1-4: GND  
J1-3: Oscillator output  
J1-2: GND  
J1-1: VCC (5 V)

5.2 32.768kHz Oscillator Circuit  
The 32.768kHz oscillator circuit is prepared on the M38517T-ADS. When using the 32.768kHz  
oscillator circuit as a sub-clock, set the short-circuit connector of the SW1 to the XCIN side.

6. Reset Circuit  
Figure 6.1 shows the reset circuit and its waveform. In this product, reset is cleared in about 100 ms  
from the instant Vcc passes about 2.1 V after having started from 0 V. When Vcc drops down to about  
2.1 V, reset turns effective.
