Clock
Input
Inputs data shift clock pulses for the shift
register. At the falling edge of each CL pulse,
the shift register shifts data input.
M

M
Input
Changes the LCD drive outputs to AC.
CH

Data
Input
Serial input (shift register data input). In 2
×
60-output mode, shift register data is input to
pins X61 to X120 in serial when SHL is low,
and to pins X1 to X60 in serial when SHL is
high. This pin must be connected to GND
when not used.
