BLOCK FUNCTION
CLOCK GENERATOR
The oscillator is operated by connecting external resistor and capacitor. The clock of oscillator block is used as
signal of common and segment driver.
FUNCTION DECODER
Function decoder generates, using chip enable (CE), data (DI), clock (CK) from controller, a signal which controls
the function and mode of chip. for example AD / DSP function , drive mode, latch clock select and so forth.
Data transfer (56 bits)
D1 D2 D3 D4 D5 D6 D7 D8 D47 D48 D49 D50 D51 D52 D53 DP DQ DR
DP : Drive mode select bit → 1 / 1 duty at "0" , 1 / 2 duty at "1" ,
DQ : AD / DSP function select bit → Segment output at "0" AD / DSP function at "1".
DR : Latch clock select bit →latch1 clock at "0", latch 2 clock at "1".
NOTE:
protect floating.
If AD / DSP function selected are not in use, ARI, ALI, DSP1, DSP2 pins are connected to VDD or VSS in order to

LATCH AND SEGMENT DRIVER
• Latch has two signal, latch 1 clock latches D1 to D52 in 1/1 duty mode or 1/2 duty mode. latch 2 clock
latches D54 to D105 in 1/2 duty mode D53 and D106 mean dummy bits ( Don't care ) at 1/2 duty mode
• If AD/DSP function is selected, S44 to S47 are input pins, S48 to S53 are output pins.
