Input/output
Chip-enable signals. Input/output switching is controlled by
the SHL signal. When these signals are used as inputs,
display data latching is performed when the input goes high.
When these signals are used as outputs, a low-to-high
transition is made at the rising edge of the 64th pulse of the
CL2 signal, and the next-stage driver is activated.

Input
Current-alternating signal, controlling liquid-crystal alternate
current drive. The M signal is input after provision of a setup
time with respect to the rise of the CL1 signal. Positive-
polarity (V0–V4) and negative-polarity (V5–V9) output
voltages are generated as shown below according to the
polarity of the latched M signal.
