C68/80

This pin is MCU parallel interface selection input. When

the pin is pulled high, 6800 series interface is selected and

when the pin is pulled low, 8080 series interface is selected.

If Serial Interface is selected (P/S pulled low), the setting

of this pin is ignored, but must be connected to a known logic

(either high or low).

P/S

This pin is serial/parallel interface selection input. When

this pin is pulled high, parallel interface mode is selected.

When it is pulled low, serial interface will be selected.

Note1: For serial mode, D0, D1, D2, D3, D4, D5, R/W/

(WR), E/(RD) is recommended to be connected to Vss.

Note2: Read Back operation is only available in parallel

mode.

IRS

This is the input pin to enable the internal resistors net-

work for the voltage regulator. When this pin is pulled high,

the internal feedback resistors of the internal regulator for

generating VL6 will be enabled.

When it is pulled low, external resistors, R1 and R2,

should be connected to VDD and VF, and VF and VL6, respec-

tively (see application circuit diagrams).

COM0 - COM33

These pins provide the row driving signal to the LCD

panel. The output voltage level of these pins is VDD during

sleep mode and standby mode.

SEG0 - SEG99

These pins provide the LCD column driving signals. The

output voltage level of these pins is VDD during sleep mode

and standby mode.

ICONS

This pin is the special icon or indicator line. There are two

ICONS pins (SSD1810A) on the chip. Both pins output exact-

ly the same signal. The reason for duplicating the pin is to en-

hance the flexibility of the LCD layout.

Note: SSD1810V has only one ICONS pin.

NC

These are the No Connection pins. Nothing should be

connected to these pins, nor they are connected together.

These pins should be left open individually.
