Note The TYP value differs depending on the setting of the oscillation stabilization time select register (OSTS).

Caution Ensure that the duty of oscillation waveform is between 45% and 55%.

Remarks 1. Connect the oscillator as close as possible to the X1 and X2 pins.

2. Do not route the wiring near broken lines.

3. Sufficiently evaluate the matching between the oscillator and resonator.

(b) External clock input

Cautions

1. Connect the high-speed CMOS inverter as close as possible to the X1 pin.

2. Sufficiently evaluate the matching between the µPD703014A, 703014AY, 703015A,

703015AY, 703017A, 703017AY and the high-speed CMOS inverter.
