Fig. 26 Clock control circuit structure
System 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 as shown Figure 27.
A feedback resistor is built-in between XIN pin and XOUT pin.
ROM ORDERING METHOD
Please submit the information described below when ordering
Mask ROM.
(1) Mask ROM Order Confirmation Form*
(2) Mark Specification Form
(3) Data to be written to ROM, in EPROM form (three identical
copies) or one floppy disk.
* For the mask ROM confirmation and the mark specifications,
refer to the “Renesas Technology Corp.” Homepage
(http://www.renesas.com/en/rom).

CLOCK CONTROL
The clock control circuit consists of the following circuits.
System clock generating circuit
Control circuit to stop the clock oscillation
Control circuit to return from the RAM back-up state
