15.1.2
An external clock signal can be input as shown in the examples in figure 15.4. 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 15.3 shows the input conditions for the external clock. When an external clock is used, the
range of usable frequencies is from 5 to 16.5 MHz and an external clock with half frequency of the
system clock (φ) should be used.
