The oscillator circuit, a Pierce oscillator, is designed to work with both, an external crystal
oscillator or an external stable clock source. It basically consists of an inverting amplifier
and a feedback element with XTAL1 as input, and XTAL2 as output.
When using a crystal, a proper external oscillator circuitry must be connected to both
pins, XTAL1 and XTAL2. The crystal frequency can be within the range of 4 MHz
to 12 MHz. Additionally, it is necessary to have two load capacitances
depending on the crystal type, a series resistor

the negative resistance evaluation and for non-productive systems. The exact values
and related operating range are dependent on the crystal frequency and have to be
determined and optimized together with the crystal vendor using the negative 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.
