(9) Set Gain and Potentiometer

Action

C/D W/R D7 D6 D5 D4 D3 D2 D1 D0

Set Gain and Potentiometer

0010000001

GN [1:0] PM [5:0]

(Double byte command)

0 0 GN1 GN0 PM5 PM4 PM3 PM2 PM1 PM0

Program Gain (GN[1:0]) and Potentiometer (PM[5:0]). See section LCD VOLTAGE SETTING for more detail.

Effective range of GN = 0 ~ 3

PM value = 0 ~ 63

(10) Set RAM Address Control

Action

Set AC [2:0]

C/D W/R D7 D6 D5 D4 D3 D2 D1 D0

0 0 1 0 0 0 1 AC2 AC1 AC0

Program registers AC[2:0] for RAM address control.

AC[0] - WA, Automatic column/page wrap around.

0: CA or PA (depends on AC[1]= 0 or 1) will stop incrementing after reaching boundary

1: CA or PA (depends on AC[1]= 0 or 1) will restart, and PA or CA will increment by one step.

AC[1] – Auto-Increment order

0 : column (CA) increment (+1) first until CA reach CA boundary, then PA will increment by (+/-1).

1 : page (PA) increment (+/-1) first until PA reach PA boundary, then CA will increment by (+1) .

AC[2] – PID, page address (PA) auto increment direction ( 0/1 = +/- 1 )

When WA=1, controls whether page address will be adjusted by +1 or -1, when CA reached CA

boundary. No effect when WA=0.

CA boundary is 240 and PA boundary is 15 when PID=0, PA boundary is 0 when PID=1.

(11) Set All Pixel ON

Action

C/D W/R D7 D6 D5 D4 D3 D2 D1 D0

Set All Pixel On DC [1]

0 0 1 0 1 0 0 1 0 DC1

Set DC[1] to force all SEG drivers to output ON signals. This function has no effect on the existing data

stored in display RAM.

(12) Set Inverse Display

Action

C/D W/R D7 D6 D5 D4 D3 D2 D1 D0

Set Inverse Display DC [0]

0 0 1 0 1 0 0 1 1 DC0

Set DC[0] to force all SEG drivers to output the inverse of the data stored in display memory. This function

has no effect on the existing data stored in display RAM.

(13) Set Display Enable

Action

C/D W/R D7 D6 D5 D4 D3 D2 D1 D0

Set Display Enable DC[2]

0 0 1 0 1 0 1 1 1 DC2

This command is for programming registers DC[2].

When DC[2] is set to 0, the IC will put itself into Sleep mode. All drivers, voltage generation circuit and timing

circuit will be halted to conserve power. When DC[2] is set to 1, UC1608 will first exit from Sleep mode,

restore the power and then turn on COM drivers and SEG drivers. There is no other explicit user action or

timing sequence required to enter or exit the Sleep mode.
