Circuit Configuration
An external clock signal can be input as shown in the examples in figure 24.5. 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, subactive mode,
subsleep mode, and watch mode.
