4. Setting Up

This chapter describes how to set up the M38517T-ADS.

Note on Setting Up:

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.

CAUTION

• Always shut OFF power before connecting this product. The power ON state could destroy internal circuits.

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).

Function

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.

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.

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.

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.

Detected power voltage (V) About 1.25 x (R3 + R4) / R4
