Crystal Oscillators / Ceramic Resonators
In XT, LP or HS modes a crystal or ceramic resonator is connected to the OSC1 and OSC2 pins
to establish oscillation
cut crystal. Using a series cut crystal may give a frequency out of the crystal manufacturer’s
specifications. When in XT, LP or HS modes, the device can have an external clock source drive
the OSC1 pin
