6. PIN DESCRIPTION
RES#
This pin is reset signal input. When the pin is low, initialization of the chip is executed.
CS#
This pin is the chip select input. The chip is enabled for MCU communication only when CS# is pulled
low.
D/C#
This pin is Data/Command control pin. When the pin is pulled high, the data at D
data. When the pin is pulled low, the data at D
relationship to MCU interface signals, please refer to the Timing Characteristics Diagrams.
E (RD#)
This pin is MCU interface input. When interfacing to a 6800-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 chip is
selected.
When connecting to an 8080-microprocessor, this pin receives the Read (RD#) signal. Data read
operation is initiated when this pin is pulled low and the chip is selected.
R/W# (WR#)
This pin is MCU interface input. When interfacing to a 6800-series microprocessor, this pin will be used as
Read/Write (R/W#) selection input. Read mode will be carried out when this pin is pulled high and write
mode will be carried out when this pin is pulled low. When 8080 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 chip is selected.
BS0, BS1, BS2
These pins are MCU interface selection input. See the following table:
Note: Unlike BS0, BS1 and BS2 are controlled by hardware connection, BS3 is controlled by software
command, A0.
