Normally, the bias voltage used is set by a resistor divider

XCK
Clock input pin for taking display data
#
Data is read on the falling edge of the clock pulse
LP
Latch pulse input pin for display data
#
Data is latched on the falling edge of the clock pulse
L/R
Direction selection pin for reading display data
#
When set to V
SS
level "L", data is read sequentially from Y160 to Y1
#
When set to V
DD
level "H", data is read sequentially from Y1 to Y160
DISPOFF
Control input pin for output deselect level
#
The input signal is level-shifted from logic voltage level to LCD driver voltage level, and controls LCD
driver circuit
#
When set to V
SS
level “L”, the LCD driver output pins (Y1 - Yl60) are set to level V
5
#
While DISPOFF is set to “L”, the contents of the line latch are reset, but the display data in the data latch
are read regardless of the condition of DISPOFF. When the DISPOFF function is canceled, the driver
outputs deselect level (V
12
or V
43
), then outputs the contents of the date latch onto the next falling edge
of the LP.
That time, if DISPOFF removal time can not keep regulation what is shown AC characteristics, can not
output the reading data correctly
FR
AC signal input for LCD driving waveform
#
The input signal is level-shifted from the logic voltage level to the driver voltage level, and controls LCD
driver circuit
#
Normally inputs a frame inversion signal
The LCD driver output pin’s output voltage level can be set to the line latch output signal and the FR signal
MD
Mode selection pin
#
When set to V
SS
level “L”, 4-bit parallel input mode is set
#
When set to V
DD
level “H", 8-bit parallel input mode is set
