When an external clock is input from the OSC1 terminal by the mask option, do not connect anything to the OSC2 terminal,
and when an external clock is input from the OSC3 terminal, do not connect to the OSC4 terminal.
When external power supply is selected by the mask option.
When LCD drive power is not used, the capacitor is not necessary.
In this case, do not connect anything to VC1 to VC5 and CA to CE terminals.
It is necessary when the panel load is large and for 1/32 duty driving.
The resistance value should be decided by connecting it to the actual panel to be used.
When CR oscillation is selected to OSC3, the maximum frequency is limited to 3 MHz.
When CR oscillation is selected to OSC3, the maximum frequency is limited to 4 MHz.
