Clock Generator

The GMS340 series has an internal clock oscillator. The oscillator circuit is

designed to operate with an external ceramic resonator. Internal capacitors are

available as a masked option. Oscillator circuit is able to organize by connecting

ceramic resonator to outside. (In order to built in capacitor for oscillation as

masked option.)

* It is necessary to connect capacitor to outside in order to change ceramic

resonator, You must examine refer to a manufacturer`s
