Note) 1 When an external clock is input from the OSC1 terminal by the mask option, leave the OSC2 terminal open,
and when an external clock is input from the OSC3 terminal, leave the OSC4 terminal open.
2 When external power supply is selected by the mask option.
3 When LCD drive power is not used, the capacitor is not necessary. In this case, leave the V
C1

C5
and CA to CG terminals open.
4 When a 1/4-bias LCD drive power supply is used, the capacitors C
