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
