4. Setting Up
This chapter describes how to set up the M38C29T-ADF.
(1) Mount the emulator MCU on the M38C29T-ADF.
After checking the position of the No. 1 pin of the emulator MCU, mount the emulator MCU referencing Figure 4.1.
(2) Insert the connector on the tip of the emulator probe to the socket on the emulator MCU.
For the M38000T2-CPE, the converter board PCA4933 is required between the emulator probe and emulator MCU.

CAUTION
Cautions to Be Taken for This Product:
ꢀAlways shut OFF power before connecting this product. The power ON state could destroy internal circuit.
(3/8)
(3) Connect the RESET cable (white) and the GND cable (black) of the emulation pod to the RESET (TP3) pin and Vss (TP2) pin of
the M38C29T-ADF respectively. And connect the Vcc cable (red) to the Vcc (TP1) pin.
(4) Set the MCU type select switch of the M38000T2-CPE to the RLSS side.
(5) Connect a power supply (not included) to the Vcc (TP1) pin of the M38C29T-ADF. And connect the GND output of the power
supply to the Vss (TP2) pin. Use the power supply whose rising time is 10ms or less.
Table 4.1 lists the correspondence of the connector cables and signals, and Figure 4.2 shows the connection pattern.

Factory-setting
PORT
SW1 PORT/XCIN Allows you to choose whether to supply the sub-clock signals (32.768kHz) to the
MCU's XCIN pin (pin 43).
To use P61/XCIN as an output port, choose the PORT side.
To use the sub-clock signals, choose the XCIN side.
SW2 VREF
Allows you to choose whether to apply Vcc or some other source to the MCU's VREF Vcc
pin (pin 21). In the case of the latter, choose the J1-21 side, and apply a voltage within
a prescribed range to the J1-21.
SW3 CNVss
SW4 XOUT
Allows you to choose which to connect, Vcc or Vss, to the MCU's CNVss pin (pin
39).
Allows you to choose whether to pull up the MCU's XOUT pin (pin 46).
To use the oscillator circuit of OSC-2 on the temporary target board, or to input the
external clock, set SW4 to Vcc to pull up XOUT pin.
Vss
Vcc
To use the oscillator circuit with a resonator between XIN and XOUT, set SW4 to NC.

5. Oscillator Circuit
5.1 Oscillator Circuit Board
The M38C29T-ADF 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.

5.2 32.768kHz Oscillator Circuit
The 32.768kHz oscillator circuit is prepared on the M38C29T-ADF. When using the 32.768kHz oscillator circuit as a sub-clock, set
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 100ms from the instant Vcc passes about
2.1V after having started from 0 V. When Vcc drops down to about 2.1V, reset turns effective.
