LCD segment driving signals are output from these pins and they should be connected to the
segment side of the LCD panel.

– In the static display mode
The nth-bit data of the data latch (A) corresponds to the SEG n. The data of the data latch
(B) is invalid .
A signal out of phase with the COM-OUT signal is output to the segment outputs when the
display is turned on, while a signal in phase with it is output when the display is turned off.
– In the 1/2 duty dynamic display mode
Output of the SEG n corresponds to as follows.
When COM-A is in select mode:
nth-bit data of the data latch (A)
When COM-B is in select mode:
nth-bit data of the data latch (B)
When the display is turned on, a signal out of phase with the common signal corresponding
to the data is output, while a signal in phase with the common signal is output when the
display is turned off.
