PIN DESCRIPTION
6.1
This pin is reset signal input. When the pin is low, initialization of the chip is executed.
RES
6.2
These 3 pins use together to determine the interface protocol between the driver and MCU according
to the following table.

6.3
This pin is chip select input. The chip is enabled for display data/command transfer only when
CS
is
low.
For 6800-series parallel mode, when E pin is pulled high, the read/write cycle is initiated by pulling low
of this
CS
pin.
CS
6.4
This input pin is to identify display data/command cycle. When the pin is high, the data written to the
driver will be written into display RAM. When the pin is low, the data will be interpreted as command.
This pin must be connected to V
SS
when 3-lines SPI interface is used.
D/
C
6.5
This pin is microprocessor interface signal. When interfacing to an 6800-series microprocessor, the
signal indicates read mode when high and write mode when low. When interfacing to an 8080-
microprocessor, a data write operation is initiated when
R/W (
WR
)
is low and the chip is selected.

6.6
This pin is microprocessor interface signal. When interfacing to an 6800-series microprocessor, a data
operation is initiated when
E(

is high and the chip is selected. When interfacing to an 8080-
microprocessor, a data read operation is initiated when
E(
