Output When FCS is high, a chip enable signal is
transferred to the next IC from this pin.
Connect this pin to ( of the next IC.
When FCS is low, open this pin.
Display off Input
When this signal is low, liquid crystal display
drive output is set at V1 level and liquid
crystal display is turned off. At this time,
internal display data is not affected. When
this signal is high, the operation returns to
the normal status.

Input/
output
Input
In column driver operation, input display
data to D0L, D1R, D2, and D3 pins.
In common driver operation, when SHL is
high, D0L and D1R pins are display data
output and input pins, respectively, and vice
versa when SHL is low. At this time, set D2
and D3 low.
When display data is high, liquid crystal
display drive output is selection level and
the display is on, and when display data is
low, they are non-selection level and off,
respectively.
Function
select
Input
Control signal to select each operating
mode.
When the FCS pin is high, the operating
mode is column driver, and when it is low,
the operation mode is common driver.
TEST
Input Test pin. Set this pin low.
Y1 to Y80
Output
Liquid crystal display drive output.
One of four levels V1 to V4 is output
according to the combination of the M
signal and display data.
See Figures 5 and 6.
