CLOCK CONTROL
The clock control circuit consists of the following circuits.
q Clock generating circuit
q Control circuit to stop the clock oscillation
q System clock selection circuit
q Instruction clock generating circuit
q Control circuit to return from the RAM back-up mode
Fig. 32 Clock control circuit structure
Fig. 33 Ceramic resonator external circuit
Clock signal f(XIN) is obtained by externally connecting a ceramic
resonator. Connect this external circuit to pins XIN and XOUT at
the shortest distance. A feedback resistor is built-in between pins
XIN and XOUT.
ROM ORDERING METHOD
Please submit the information described below when ordering
Mask ROM.
(1) M34570M4-XXXFP Mask ROM Order Confirmation Form,
M34570M8-XXXFP Mask ROM Order Confirmation Form, or
M34570MD-XXXFP 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
The wait time control circuit is automatically used to generate the time required to stabilize the
f(XIN) oscillation.

Externally connect a
damping resistor Rd
depending on the
oscillation frequency.
(A feedback resistor is
built-in.)
Use the resonator
manufacturer’s
recommended value
because constants such
as capacitance depend
on the resonator.
