Clock signal f(X

IN

) is obtained by externally connecting a ceramic

resonator.

Connect this external circuit to pins X

IN

 and X

OUT

 at the shortest

distance. A feedback resistor is built in between pins X

IN

 and X

OUT

.

When an external clock signal is input, connect the clock source to

X

IN

 and leave X

OUT

 open. When using an external clock, the maxi-

mum value of external clock oscillating frequency is shown in Table

24.

such as capacitance de-
pend on the resonator.
