CS#
I Chip Select
This is the chip select input. The chip is enable for MCU
communication only when CS# is pulled low.
8
RES#
I Power Reset for Controller and Drive
This is reset signal input. When the pin is low , initialization of the chip
is executed.
9
D/C#
I Data/ Command Control
This pin is Data/Command control pin. When the pin is pulled high, the
input at D0~D7 is treated as display data. When the pin is pulled low,
the input at D0~D7 will be transferred to the command register.
10
W/R#
I Write or Read/Write Select
(R/W#)
When 80xx interface mode is selected, the pin will be the Write (WR#)
input.
When interfacing to a 68xx-series microprocessor, the pin will be used
as Read/Write (R/W#) selection input. Pull this pin to “High” for read
mode and pull it to “Low” for write mode.
11
RD#(E) I Read or Read/Write Enable
When 80xx interface mode is selected, the pin will be the Read (RD#)
input.
When interfacing to a 68xx-series microprocessor, the pin will be used
as the Enable (E) signal. Read/Write operation is initiated when this pin
is pulled high and the CS# is pulled low.

VSS
I Host Data Input /Output Bus
These pins are 8-bit bi-directional data bus to be connected to the
microprocessor’s data bus. When serial mode is selected, D1 will be the
serial data input SDIN and the D0 will be the serial clock input SCLK.
When 12C mode is selected, D2 & D1 should be tired together and serve
as SDAout & SDAin in application and D0 is the serial clock input SCL.
G Ground for System
This is a ground pin. It must be connected to external source.

VCC-C I OLED Driver Power Supply ON/ OFF Control
TL
When this pin is pulled high, the panel power supply will be turned ON.
When this pin is pulled low, the panel power supply will be turned OFF.

VCC
P Voltage Output High Level for COM Signal
This pin is OLED driver power supply. When VCC-CTL is pulled
high, the pin will be output about 9V voltage (Built in Panel Power
Supply).
