resistance method. Oscillation measurement with the final target system is strongly
recommended to verify the input amplitude at XTAL1 and to determine the actual
oscillation allowance (margin negative resistance) for the oscillator-crystal system.
When using an external clock signal, the signal must be connected to XTAL1. XTAL2 is
left open (unconnected).
The oscillator can also be used in combination with a ceramic resonator. The final
circuitry must also be verified by the resonator vendor.

mode and external input clock mode.
