REGISTERS DESCRIPTION
(1) Address 12016
Set display frequency by frequency
value setting. Set N1 to be “N1=fOSC/
fH”.
fOSC(MHz) : External clock frequency
for TCK pin (=display fre-
quency)
fH(kHz) : Horizontal synchronous sig-
nal frequency for HOR pin
Set registers DIVS0, DIVS1 (address
12016), RSEL0 (address 12116) and
RSEL1 (address 12216) according to
external clock frequency.
For details, see (2) Setting display fre-
quencies under Register Supplemen-
tary Description.
Any of this settings above is reguired
only when EXCK1=1, EXCK0=1.
