| 1 | VB1- | PWR | LCD Bias Voltages. These are the voltage source to provide SEG driving currents. These voltages are generated internally. Connect capacitors of CBX 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. |

| 6 | VBIAS | I | This is the reference voltage to generate the actual SEG driving voltage. VBIAS can be used to fine tune VLCD by external variable resistors. Internal resistor network has been provided to simplify external trimming circuit. In COF application, connect a small bypass capacitor between VBIAS and VSS to reduce noise. |

| 17 | WR1 | I | WR[1:0] controls the read/write operation of the host interface. See Host Interface section for more detail. In parallel mode, 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 them to VSS. |

| 20 | RST | I | When RST=”L”, all control registers are re-initialized by their default states. Since UC1608x has built-in Power-ON-Reset and Software Reset command, RST pin is not required for proper chip operation. When RST is not used, connect the pin to VDD. |
