Clock signal f(X

) 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.

ROM ORDERING METHOD
Please submit the information described below when ordering
Mask ROM.
(1) Mask ROM Order Confirmation Form ..................................... 1
(2) Data to be written into mask ROM ...............................EPROM
(three sets containing the identical data)
(3) Mark Specification Form .......................................................... 1

Fig. 43 External clock input circuit
Note: Externally connect a
damping resistor Rd de-
pending on the oscillation
frequency.
(A feedback resistor is
built-in.)
Use the resonator manu-
facturer’s recommended
value because constants
such as capacitance de-
pend on the resonator.
