An external clock signal can be input as shown in the examples in figure 23.4. If the XTAL pin is
left open, make sure that parasitic capacitance is no more than 10 pF. When the counter clock is
input to the XTAL pin, make sure that the external clock is held high in standby mode.
Table 23.3 shows the input conditions for the external clock. When an external clock is used, the
range of its frequencies is from 8 to 25 MHz.
