2. Interface Pin Function
No. Symbol Function
1 NC(GND) No connection
2 VLSS This is an analog ground pin
3 VSS Ground.
4 NC No connection
5 VDD Power supply pin for core logic operation
6 BS1
MCU bus interface selection pins. Select appropriate logic setting as
described in the following table. BS2, BS1 and BS0 are pin select
Note
(1) 0 is connected to VSS
(2) 1 is connected to VDD
7 BS2
8 CS#
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).
9 RES#
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.
10 D/C#
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 3-
wire serial interface is selected, this pin must be connected to
VSS.
11 R/W#
This pin is read / write control input pin connecting to the MCU
interface.
When 6800 interface mode is selected, 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 when 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.
When serial or I2C interface is selected, this pin must be connected to
VSS.
