(2) Setting display frequencies
Set a display frequency by setting a frequency value for the hori-
zontal synchronization signal by use of DIV10 to DIV0 (12016).
Set display frequency area in conformity with the frequency of the
external clock signal.
Set display frequency area by use of DIVS0, DIVS1 (12016),
RSEL0 (12116), and RSEL1 (12216). Frequency area are as fol-
lows.

Cautions in setting a display frequency
To change the external clock frequency or the horizontal synchroni-
zation frequency, follow the steps in sequence given below.
(a) Display OFF
(DSPON = 0)
(b) Set the display frequency
(Use DIV10 to DIV0 (12016),
DIVS0, DIVS1 (12016), RSEL0
(12116), and RSEL1 (12216).)
(c) 20-ms waiting time with the horizontal synchronization signal and
the external clock signal being input
(d) Display ON
(DSPON = 1)
