Common output signals for character display: COM1 to
COM8 for the first line, COM9 to COM16 for the second
line. All the unused pins output deselection waveforms.
During sleep mode (SLP= 1) or standby mode (STB = 1), all
pins output V
CC
level.
Segment output signals for segment icon display and
character display. During sleep mode (SLP = 1) or standby
mode (STB = 1), all pins output V
CC
level.
Common output signal for annunciator display; can drive
display statically between V
and AGND levels; outputs V
CC
level while annunciator display is turned off (DA = 0).
Segment output signals for annunciator display; can drive
display statically between V
and AGND levels; output V
CC
level while annunciator display is turned off (DA = 0).
V2/V3 are voltage levels for the internal operational
amplifiers. These V2 and V3 are short-circuited when 1/4
bias LCD driving. And these V2 and V3 are open when 1/5
bias LCD driving.
Used for output from the internal operational amplifiers
when they are used (OPOFF = GND); when amplifiers'
driving capability is insufficient, attach a capacitor to
stabilize the output. Especially these capacitors for V1OUT
and V4OUT must be attached. When the amplifiers are not
used (OPOFF = V
); V1 to V5 voltages can be supplied to
these pins externally.
Adjusts the driving capability of the internal operational
amplifiers according to the LCD power supply voltage.
