CS1=”H”. When the chip is not selected, D[7:0] may be
high impedance.

RST is not used, connect the pin to VDD.

RD/WR(WR[1:0]) controls the read/write operation of the host interface.

In parallel mode, RD/WR(WR[1:0]) meaning depends on whether the interface is

in the 6800 mode or the 8080 mode. In serial interface modes, these two pins are

not used. Connect to VSS.

Bi-directional bus for both serial and parallel host interfaces.

In S8 and S9 mode, connect unused pins to VDD or VSS.

VDD2&3 is the analog power supply and it should be connected to the same power

source. Minimize the trace resistance for VDD2&3.

LCD Bias Voltages. These are the voltage sources to provide SEG driving currents.

These voltages are generated internally. Connect capacitors of CBX value between

VBX+ and VBX–. The resistance of these four traces directly affects the SEG

driving strength of the resulting LCD module. Minimize the trace resistance is

critical in achieving high quality image.

connect CL between VLCD and VSS, and keep the trace resistance under 300

Ohm.
