8. RESET CIRCUIT

Setting RESB to

“L” can initialize internal function. While RESB is “L”, no instruction can be accepted. RESB pin must

connect to the reset pin of MPU and initialization by RESB pin is essential before operating.

When RESB becomes

“L”, the following procedures will start.

Power Down Mode: PD=1 (Analog Power OFF, Oscillator OFF & COM/SEG output at VSS)

Page Address: Y[3:0]=0

Column Address: X[6:0]=0

COM Scan Direction: Depends on

“TMY” setting

SEG Select Direction: Depends on

“TMX” setting

Display Control: Display OFF: D=E=0

Basic Instruction Set: H=0

Initial V0 Setting: V0[4:0]=0

Bias: Depends on

“BR” setting

After power-on, RAM data are undefined and the display status is

“Display OFF”. It’s better to initialize whole DDRAM (ex:

fill all 00h or write the display pattern) before turning the Display ON.
