Clock and timing characteristics
Crystal / ceramic resonator oscillator
The STR73xF can operate with a crystal oscillator or resonator clock source.
simple model of the internal oscillator driver as well as example of connection for an oscillator or a
resonator.

XTAL2 must not be used to directly drive external circuits.
For test or boot purpose, XTAL2 can be used as an high impedance input pin to provide an
external clock to the device. XTAL1 should be grounded, and XTAL2 connected to a wave
signal generator providing a 0 to VDD signal. Directly driving XTAL2 may results in
deteriorated jitter and duty cycle.
