Output
When FCS is high, a chip enable signal is
transferred to the next IC from this pin.
Connect this pin to the next IC.
When FCS is low, open this pin.

Input
In serial-latch operation, DIOL, DIOR, DR,
and DL are display data input and open pins.
When the SHL pin is high, DL is low and DR
is input, and when it is low, DL is input and
DR is low. At this time, set the DIOL and
DIOR pins low.
In shift register operation, DIOL, DIOR, DR,
and DL are display data input and output
pins. When the SHL pin is high, DIOL and
DIOR are output and input, respectively, and
vice versa when the SHL pin is low. At this
time, set the DR and DL pins low.
When display data is high, liquid crystal
display drive output is selection level and the
liquid crystal display is on, and when display
data is low, they are non-selection and off,
respectively.
FCS

Function
select
Input
Control signal to select each operating mode.
When the FCS pin is low, the operating mode
is shift register, and when it is high, the
operating mode is serial latch.

Output
Each Y pins outputs one of the four voltage
levels V1, V2, V3, or V4 according to the
combination of M and display data. The
combination is differently between serial latch
operation and shift register operation. See
Figure 5. In case of using at display expanse
of LCD-II family, use in shift register operation
(FCS = L).
Note:
Pin numbers of the HD66002TE are enclosed in parentheses ( ).
