Technical Data
General Description
required to provide reliable startup and maximum stability. The load
capacitance values used in the oscillator circuit design should include all
stray layout capacitances. To minimize output distortion, mount the
crystal and capacitors as close as possible to the pins.
NOTE:
Use an AT-cut crystal and not an AT-strip crystal. The MCU may
overdrive an AT-strip crystal.
