33 / 289 page  CHAPTER 2 PIN FUNCTIONS 18 2.4 CAUTIONS ON USE OF THE RESET AND INT PINS (in Normal Operation Mode only) In addition to the function described in 2.1 PIN FUNCTIONS, the RESET pin and the INT pin have the function (for IC testing only) of setting test mode for testing the internal operation of the µPD17120 subseries. If a voltage exceeding the VDD is applied to either of these pins, test mode is set. Therefore, adding a noise exceeding VDD even in normal operation may result in placing the pin in test mode, thus impeding normal operation. For example, if the RESET or INT pin wires are laid out too long, wiring noise is added to these pins, thus causing the above problem. Therefore, make sure that the wires are laid down in such a manner that such inter-wire noises are suppressed as much as possible. If noise is still a problem, take noise countermeasures based on external parts as shown in the illustrations below. • Connecting a Diode of Small VF between VDDs • Connecting a Capacitor between VDDs VDD RESET, INT VDD Diode whose VF is small VDD RESET, INT VDD |
