Power supply voltage for liquid crystal display
drive level.
See Figure 3.
Column driver data latch signal. Data is
latched at the falling edge of this signal. Set
this signal low in common driver operation.
In column driver operation, used as a display
data latch signal.
In common driver operation, used as a line
selection data shift signal.
In both operations, this signal is valid at its
falling edge.
AC conversion signal for liquid crystal display
drive output.
Control signal for inverting data output
destination.
1. In column driver operation
See Figure 4.
2. In common driver operation
SR1, SR2, SR3, ...., SR80 correspond to Y1,
Y2, Y3, ...., Y80 outputs.
When SHL is low, data is input to D0L pin and
output from D1R pin. D2 and D3 are set low.
When SHL is high, the relationships between
D0L and D1R are reverse.
See Table 2.
When FCS is high, data latch starts by setting

The relationships between the
FCS signal, data latch operation, and driver
function are as show in Table 3
