Function
Logic system power supply pin connects to +2.4 to +5.5V
Ground pin connects to 0 V
Power supply pin for LC driver voltage bias.
. Normally, the bias voltage used is set by a resistor divider.
. Ensure that voltage are set such that V

. To further reduce the difference between the output waveforms of LC driver
output pins Y
1
and Y
160
, externally connect V
iR
and V
iL
(I = 0, 12, 43, 5)

.
Clock input pin for taking display data
. Data is read on the falling edge of the clock pulse.
Latch pulse input pin for display data
. Data is latched on the falling edge of the clock pulse.
Direction selection pin for reading display data
. When set to V
SS
level “L”, data is read sequentially from Y
240
to Y
1
.
. When set to V
DD
level H”, data is read sequentially from Y
1
to Y
240
.
Control input pin for output deselect level
. The input signal is level-shifted from logic voltage level to LC drive voltage
level, and controls LC drive circuit.
. When set to V
SS
level “L”, the LC drive output pins (Y
1
- Y
240
) are set to level
V
5
.
. While set to “L”, the contents of the line latch are reset, but read the display
data in the data latch regardless of condition of DISPOFFB.
When the DISPOFFB function is canceled, the driver outputs deselect level
(V
12
or V
43
), then outputs the contents of the data latch on the next.
Falling edge of the LP. That time, if DISPOFFB removal time can not keep regulation what is
shown AC characteristics (page 21), can not output the reading data correctly.
