NC
XIN
No Connection
The crystal oscillator pin XIN supports parallel resonant AT cut fundamental frequency crystals and ceramic resonators.
XIN can also be an input if there is an external clock source instead of a crystal.
The crystal oscillator pin XOUT supports parallel resonant AT cut fundamental frequency crystals and ceramic resonators.
XOUT serves as the output of the crystal amplifier.
Digital Ground
A HIGH on the reset input for two t
