Display Timing at Normal mode (not reverse mode), 1/128 DUTY.
This driver circuit generates four levels of LCD driver voltage. The circuit has 384-segment
output and 130-common output and outputs a combined display data and internal signal M.
Two of the common outputs, COMA and COMB, are special outputs. The COMA and
COMB outputs are not influenced by partial setting, they are mainly used for display. The
common driver circuit that has shift register sequentially outputs common scan signals.
