COM Signal
:
The number of COM pins varies according to the duty cycle in use as shown in
the following table. In 1/8 Duty mode COM8 must be opened. In 1/9 Duty
mode COM0 ~ COM8 pins must be used.

SEG Signal
:
The 40 segment signal pins are connected to the corresponding display RAM
address 14h to 3Bh. When Duty mode is at 1/8, the required data address are
only those from Com0 ~ Com7 (located within 14h ~ 3Bh). However, when
Duty mode is at 1/9, all data address from Com0 ~ Com7 (located within 14h ~
3Bh) and Com8 (located within 54h ~ 7Bh) are needed.
When a bit of display RAM is 1, a select signal is sent to the corresponding segment pin, and
when the bit is 0, a non-select signal is sent to the corresponding segment pin.
COM, SEG, and Select/Non-Select signals are illustrated below.
