amplifier (XTAL1, XTAL2), which can be configured for use as an on-chip oscillator.
When driving the device from an external clock source, XTAL2 should be left disconnected
and XTAL1 should be driven.
At start-up, the external oscillator may encounter a higher capacitive load at XTAL1 due to
interaction between the amplifier and its feedback capacitance. However, the capacitance
will not exceed 15 pF once the external signal meets the V
