4.2 Mounting the M38C89MF-xxxFP/M38C89EFFP
(1) Mounting parts
Mount the socket for IC1 and the oscillator circuit part. Table 4.2 lists the applicable parts for this
board.
Table 4.2 Socket for the M38C89MF-xxxFP/M38C89EFFP and applicable oscillator circuit
(2) Mounting the M38C89MF-xxxFP/M38C89EFFP
To mount the M38C89MF-xxxFP/M38C89EFFP, remove the emulator MCU and install the
M38C89MF-xxxFP/M38C89EFFP in the IC1 socket. Align pin No. 1 with the printed mark.
(3) Setting jumpers (JP)
Set the jumpers (J1 to J4 and J7) according to your applications. Table 4.3 describes the functions
of the jumpers.

• Short-circuit: OSCSEL = "L"
Selects the oscillation by ceramic resonator
• Open: OSCSEL = "H"
Selects the RC oscillation

(4) Connecting a power supply
Connect a power supply (not included) to the board's VccM power supply test (large) pin and
GND. Power is supplied to Vcc of IC1 and IC2.
To use the VccU universal power supply, connect a power supply (not included) to the VccU
power supply test pin.
VccM and VccU are not connected on the board. They can be connected by short-circuiting
jumper JP7.
