Pin Name

CLS

I/O

Function

Terminal to select whether or enable or disable the display clock internal

oscillator circuit.

I

CLS = “H” : used Internal oscillator circuit .

CLS = “L” : used external clock input .(internal oscillator is disable)

When CLS = “L”, input the display clock through the CL terminal.

M/S

I

This pin set to VDD

This is the display clock input terminal

The following is true depending on the M/S and CLS status.

IRS

This is the output terminal for the static drive.

O This terminal is only enabled when the static indicator display is ON

1

and is used in conjunction with the FR terminal.

This terminal selects the resistors for the V5 voltage level adjustment.

IRS = “H”: Use the internal resistors

I IRS = “L”: Do not use the internal resistors. The V5 voltage level is

1

regulated by an external resistive voltage divider attached to the VR terminal

drive.

/HPM = “H”: Normal mode

/HPM = “L”: High power mode

These pins are DUTY selection.
