Section 18 Clock Pulse Generator
18.3.2
Circuit Configuration: An external clock signal can be input as shown in the examples in figure
18.5. If the XTAL pin is left open, make sure that stray capacitance is no more than 10 pF.
In example (b), make sure that the external clock is held high in standby mode.
