19.2.2
Circuit Configuration: An external clock signal can be input as shown in the examples in figure
19.5. If the XTAL pin is left open, the stray capacitance should not exceed 10 pF. If the stray
capacitance at the XTAL pin exceeds 10 pF in configuration a, use configuration b instead and
hold the clock high in standby mode.
