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.
