Functions
General output ports. These ports cannot drive
current such as for LEDs or backlighting control.
Boost the current using an external transistor.
Two common output signals for segment-icon
display.
Common output signals for character/graphics
display: COM1 to COM8 for the first line; COM9 to
COM16 for the second line, and COM17 to COM24
for the third line. All the unused pins output
deselection waveforms. In the sleep mode (SLP = 1)
or standby mode (STB = 1), all pins output GND
level.
The CMS bit can change the shift direction of the
common signal. For example, if CMS = 0, COM1/24
is COM1. If CMS = 1, COM1/24 is COM24.
Segment output signals for segment-icon display and
character/graphics display. In the sleep mode (SLP =
1) or standby mode (STB = 1), all pins output GND
level.
The SGS bit can change the shift direction of the
segment signal. For example, if SGS = 0, SEG1/72
(96) is SEG1. If SGS = 1, SEG1/72 (96) is SEG72
(96).
Used for output from the internal operational
amplifiers when they are used (OPOFF = GND);
attach a capacitor to stabilize the output. When the
amplifiers are not used (OPOFF = V
), V1 to V5
voltages can be supplied to these pins externally.

: +1.8 V to +5.5 V; GND (logic): 0 V
For R-C oscillation using an external resistor, connect
an external resistor. For R-C oscillation using an
internal resistor, connect R1–R3 to OSC2 and leave
OSC1 disconnected. For external clock supply, input
clock pulses to OSC1.
For R-C oscillation using an internal resistor, adjust
the internal resistor value. Fluctuation of the resistor
value is
±
30% of the reference value. Care must be
taken to avoid fluctuation of the frame frequency in
crystal display drive operation.
Inputs a reference voltage and supplies power to the
booster; generates the liquid crystal display drive
voltage from the operating voltage.
