Input
Dual mode data input pin
According to the data shift direction of the
data shift register, data can be input
starting from the 8lst bit.
When the chip is used as Dual mode, DI7
will be pull-down.
When the chip is used as Single mode
DI7 won’t pull -down.

Input
AC signal input for LCD driving waveform
The input signal is level-shifted from logic
voltage level to LCD drive voltage level,
and controls LCD drive circuit.
Normally inputs a frame inversion signal
The LCD driver output pin’s output
voltage level can be set using the line
latch output signal and the FR signal.

Input
Control input pin for output deselect level
The input signal is level-shifted from logic
voltage level to LCD drive voltage level
and controls LCD drive circuit.
Set to Vss, LCD drive output pins are set
to Vss.
Set to Vss, the contents of the line latch
are reset, but read the display data in the
data latch regardless of condition of
DISPLAY, When DISPLAY function is
cancelled, the driver outputs deselect level
(V12 or V34), then outputs the contents of
the data latch on the next falling edge of
the LP, That time if DISPLAY removal
time can not keep regulation what is
shown AC characteristics, can not output
the reading data correctly.
