FUNCTIONAL DESCRIPTIONS

Time Base

A 4.194304MHz crystal oscillation circuit (including an amplifier and a feedback resistor) is built in the LSI

* Keep the crystal and external capacitors as close to this LSI as possible to minimize wiring for connections.

* The values of external components, such as a crystal and capacitors, should be determined including capacitance

of user's circuit boards. It is recommended to contact a crystal manufacturer.
