Function
DISPOFF
Control input pin for output deselect level
"
The input signal is level-shifted from the logic voltage level to the LCD driver voltage level, and controls
the LCD driver circuit
"
When set to V
SS
level “L”, the LCD driver output pins (Y
1
-Y
240
) are set to level V
5
"
While set to “L”, the contents of the shift resister are reset and are not reading data. When the DISPOFF
function is canceled, the driver outputs deselect level (V
12
or V
43
), and the shift data is read on the falling
edge of the LP. That time, if DISPOFF removal time can not keep regulation what is shown AC
characteristics, the shift data is not reading correctly
FR
AC signal input for LCD driving waveform
"
The input signal is level-shifted from logic voltage level to the LCD driver voltage level, and it controls the
LCD driver circuit
"
Normally, inputs a frame inversion signal
The LCD driver output pin’s output voltage level can be set using the shift register output signal and the FR
signal
MD
Mode selection pin
"
When set to V
SS
level “L”, Single Mode operation is selected. When set to V
DD
level “H”, Dual Mode
operation is selected
D
7
Dual Mode data input pin
"
According to the data shift direction of the data shift register, data can be input starting from the 121st bit
When the chip is used as Dual Mode, D
7
will be pulled-down
When the chip is used as Single Mode, D
7
won’t be pulled-down
S/C
Segment mode/common mode selection pin

When set to V
SS
level “L”, common mode is set
