DB7
Bi-direction data bus,In serial modes, connect DB[0] to SCK, DB[3] to SDAI for write and DB[5:4] to SDAO for read. SDAI and SDAO may be connected together if necessary. Connect unused pins to VSS.

CS0
Chip select input pin, low active

CD
Select Control data or Display data for read/write operation.
"L”: Control data "H": Display data/command
13
WR0
WR[1:0] controls the read/write operation of the host interface.
In parallel mode, WR[1:0] meaning depends on whether the interface is in the 6800mode or the 8080 mode. In serial interface modes, these two pins are not used,connect them to VSS.

WR1
15
BM0
Bus mode: The interface bus mode is determined by BM[1:0]:
8080 (8-bit) Mode: BM1=1; BM0=0
6800 (8-bit) Mode: BM1=1; BM0=1
4-Wire SPI Mode: BM1=0; BM0=1
2-Wire I2C Mode: BM1=0; BM0=0

BM1
17
ID
ID pin is for production control. The connection will affect the content of PID when using the Get Status command. Connect to VDD for “H” or VSS for “L”.
18
VSS
Voltage supply input pin (0V)
19
VDD
Voltage supply input pin (+3.3V)
20
VLCD
High voltage LCD Power Supply.
Capacitor CL should be connected between VLCD and VSS.
21
VB0-
LCD Bias Voltages. These are the voltage sources to provide SEG driving currents.
These voltages are generated internally. Connect capacitors of CBX of values
