NOTES:
1. Y1 is a parallel-resonant type crystal. (See table)
2. The nominal values for C1 and C2 shown are for
a crystal specified at 12.5 pF load capacitance (CL).
3. The values for C1 and C2 are dependent upon
the cystal's specified load capacitance and PCB
stray capacitance.
4. R1 must be in the circuit.
5. Ground connections should be short and return
to the ground plane which is connected to the
processor's core ground pins.
6. Tolerance for R1, C1, C2 is
5%.
