Frame Frequency Triggering Signal
This pin will send out a signal that could be used to identify the
driver status. Nothing should be connected to this pin. It should
be left open individually.

Communicating Protocol Select
These pins are MCU interface selection input. See the following
table:

RES#
I
Power Reset for Controller and Driver
This pin is reset signal input. When the pin is low, initialization
of the chip is executed.
19
CS#
I
Chip Select
This pin is the chip select input. The chip is enabled for MCU
communication only when CS# is pulled low.
18
D/C#
I Data/Command Control
This pin is Data/Command control pin. When the pin is pulled
high, the input at D7~D0 is treated as display data.
When the pin is pulled low, the input at D7~D0 will be
transferred to the command register. For detail relationship to
MCU interface signals, please refer to the
Timing Characteristics Diagrams.
14
E/RD#
I
Read/Write Enable or Read
This pin is MCU interface input. When interfacing to a
68XX-series microprocessor, this 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.
When connecting to an 80XX-microprocessor, this pin receives
the Read (RD#) signal. Data read operation is initiated when
this pin is pulled low and CS# is pulled low.
When serial mode is selected, this pin must be connected to
VSS.
15
R/W#
I
Read/Write Select or Write
This pin is MCU interface input. When interfacing to a
68XX-series microprocessor, this 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.
When 80XX interface mode is selected, this pin will be the
Write (WR#) input. Data write operation is initiated when this
pin is pulled low and the CS# is pulled low.
When serial mode is selected, this pin must be connected to
VSS.
