2. Outline
The M38C89T-ADF is a temporary target board used to develop software with a PC4701 emulator
system. It supplies to the M38C89RLFS 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. A block diagram of the M38C89T-ADF is shown in Figure 2.1.
IC1 has a pattern for mounting a socket for an M38C89MF-xxxFP/M38C89EFFP. This makes it
possible for this board to debug programs using an emulator MCU in IC2 or execute programs using
an M38C89MF-xxxFP/M38C89EFFP. A socket for M38C89MF-xxxFP/M38C89EFFP and parts
for an LCD bias circuitry are not mounted. Mount them as necessary.
Expansion boards can be installed in the through-holes of connectors J2, J3 and J4. Spacing between
connectors is given in Figure 2.1. Keep connector location in mind when making expansion boards.
Use 2.54-mm-pitch connectors. For pin array, see Table 8.1.

4. Setting Up
This chapter describes how to set up the M38C89T-ADF.
With this product, the debugging with an emulator MCU and M38C89MF-xxxFP/M38C89EFFP is
possible. Use the M38C89T-ADF mounting one of these MCUs.
To use an emulator MCU:
Read "4.1 Connecting to the Emulator" (this page)
To use the M38C89MF-xxxFP/M38C89EFFP:
Read "4.2 Mounting the M38C89MF-xxxFP/M38C89EFFP" (page 8)
CAUTION
Note on Setting Up:
• Always shut OFF power before connecting the M38C89T-ADF.
• Do not mount the IC1 and IC2 at the same time. Mount either of them only.
4.1 Connecting to the Emulator
(1) Mounting the emulator MCU
Mount the emulator MCU in the IC2 socket on the M38C89T-ADF.
Raise the socket's clamp and insert the emulator MCU flush against the socket's left and bottom
sides, placing the "•" marking on the emulator MCU at the right bottom corner. Then, lower the
clamp to lock the emulator MCU in place.
If your emulator MCU does not have the "•" marking on it, use one pin (back of the MCU) for
positioning as shown below.
MCUs have 20 x 20 pins to the socket's 21 x 21 holes. Since there are more socket holes to MCU
pins, insert the MCU flush against the socket's left and bottom sides. The socket is taped to prevent
improper MCU mounting. Do not peel off the tape.
Figure 4.1 Mounting the emulator MCU on the M38C89T-ADF
(2) Connecting the emulation probe
Insert the connector on the tip of the emulation pod probe to the J1 of this board. For the direction,
see Figure 4.2.
(3) Setting the emulation pod (M38000TL2-FPD)
As the applicable emulator MCU (M38C89RLFS) for this product is RLFS type, set the switch
on the side of the emulation pod to RLSS/RLFS side.

(4) Connecting the control signal lines
Connect the three lines of the emulation pod to the test pins.
VCC cable (yellow) ........... VccM (test pin with a yellow bead)
GND cable (black) ............. GND (test pin with a black bead)
Reset cable (white)............. RESET (test pin with a white bead)

5. Oscillator Circuit
5.1 Main Clock Generator Circuit
The main clock of 4.0 MHz is mounted (X2 only). Figure 5.1 shows the main clock generator circuit.
Figure 5.1 Main clock generator circuit
5.2 Sub Clock Generator Circuit
The sub clock generator circuit is shown in Figure 5.2. The sub clock oscillates at 32.768 kHz.
Capacitors C19 and C20 have a capacitance of 10 pF, while resistor R11 has a resistance of 0 Ω and
resistor R12 a resistance of 6.8 MΩ. Components are not mounted on the IC1 side.
If MCU power supply voltage is low, it will take time for sub clock oscillation to stabilize. Be aware
of this when changing from the main clock to the sub clock.

5.3 How to Use the RC Oscillator Circuit
The clock selection circuit is shown in Figure 5.3. Oscillation can be switched between RC oscillation
and the oscillator by changing the jumpers. The following procedure explains how to switch to RC
oscillation.
(1) Cut jumper JP4. (When JP4 is cut, the OSCSEL pin becomes high.)
(2) To enable RC oscillation in IC1, set resistor R1 (see Table 4.3) in jumpers JP1 and JP2
described in Figure 5.1. To enable RC oscillation in IC2, set resistor R10 (see Table 4.1) in
jumpers JP5 and JP6 described in Figure 5.1.

6. Reset Circuit
Figure 6.1 shows the reset circuit. The reset circuit is common for IC1 and IC2.
