8 VDDIO P Low voltage power supply and power supply for interface
logic level in both L
ow Voltage I/O and 5V I/O application. It
should match with the MCU interface voltage level and must
be connected to external source.
9 BS0 I MCU bus interface selection pins. Select appropriate logic
setting as described in the following table. BS2, BS1 and
BS0 are pin select.
Bus Interface selection
Note
(1) 0 is connected to VSS
(2) 1 is connected to VDDIO

11 BS2
12 GPIO I/O It is a GPIO pin. Details refer to OLED command DCh.
13 CS# I This pin is the chip select input connecting to the MCU.
The chip is enabled for MCU communication only when CS#
is pulled LOW (active LOW).
In I2C mode, this pin must be connected to VSS.
14 RES# I This pin is reset signal input.
When the pin is pulled LOW, initialization of the chip is
executed.
Keep this pin pull HIGH during normal operation.
15 D/C# I This pin is Data/Command control pin connecting to the
MCU.
When the pin is pulled HIGH, the data at D[7:0] will be
interpreted as data.
When the pin is pulled LOW, the data at D[7:0] will be
transferred to a command register.
In I2C mode, this pin acts as SA0 for slave address
selection.
When serial interface is selected, this pin must be connected
to VSS.
