VCC 3 OLED drive voltage +14V (Don’t care.)
D/C# 4
Data/Command Select. This is the Data/Command control pin. When it
is pulled HIGH, the input at D7-D0 is treated as display data. When it is
pulled LOW, the input at D7-D0 is transferred to the command
registers. For detail relationship to MCU interface signals, please refer
to the Timing Characteristics Diagrams.
R/W# 5
This is a MCU interface input pin. When 6800-series Parallel Interface
mode is selected, this pin is used as Read/Write (R/W) selection input.
Pull this pin to HIGH for read mode and pull it to LOW for write mode.
When 8080-series Parallel Interface mode is selected, this pin is used
as Write (WR#) selection input. Pull this pin to LOW for write mode.
Data write operation is initiated when this pin is pulled LOW and the
CS# is pulled LOW.
E(RD#) 6
This is a MCU interface input pin. When 6800-series Parallel Interface
is selected, this pin is used as Enable (E) signal. Read/Write operation
is initiated when this pin is pulled HIGH and the CS# pin is pulled
LOW. When 8080-series Parallel Interface is selected, this pin is used
to receive the Read Data (RD#)signal. Data read operation is initiated
when this pin is pulled LOW and CS# pin is pulled LOW.
D0-D7 7-14
These are 8-bit bi-directional data bus to be connected to the
microprocessor’s data bus. When serial interface mode is selected, D1
will be the serial data input, SDIN, and D0 will be the serial clock input,
SCLK.
CS# 15 Chip Select,active low
RES# 16 Reset,active low
M80/68# 17
These are MCU interface input selection pins. S003 & S005 only have
8-bit 8080-Databus and series peripheral interface. See the following
table for selecting different interfaces:
