Input
Power supply voltage for liquid crystal display
drive level.
See Figure 4.
Control signal
CL1
38 (36)
Clock 1
Input
Display data latch signal. Data is latched at the
falling edge of this signal.
CL2
49 (47)
Clock 2
Input
Display data latch and shift signal. This signal is
valid at its falling edge.
M

M
Input
AC conversion signal for liquid crystal display
drive output.
SHL
40 (38)
Shift left
Input
Control signal for inverting data output
destination.
1. Operating mode: Serial-latch operation
When serial data is input in order from D1 to
D80, the relationship between data and
output Y are as shown in Table 2.
When SHL is low, data is input from the DL pin,
and the DR pin is set low.
When SHL is high, data is input from the DR
pin, and DL pin is set low.
2. Operating mode: Shift register operation
When serial data is input in order from D1 to
D80, the relationship between data and
output Y are as shown in Table 3.
When SHL is low, data is input to the DIOL pin,
and output from the DIOR pin.
When SHL is high, the relationships between
DIOL and DIOR are reverse.
E
31 (29)
Enable
Input
When FCS is high, data latch starts by setting
the
E
signal low.
When FCS is low, set the
E
signal high.
The relationships between the
E
signal, the
FCS signal, and data latch operation are as
shown in Table 4.
