4.6 Oscillation Circuit
The oscillation circuit incorporates a clock oscillator which generates a system clock and an
internal clock. There are two methods to supply a clock; one is to connect a ceramic oscillator,
and the other is to input an external clock.
When using the ceramic oscillator, we recommend the CSTCS16.00MXOC3 (With capacitor)
made by MURATA. When inputting the external clock, you may either open the XTAL
terminal or input an antiphase clock to the XTAL terminal.
